bouncy egg

# data[].attributes.attachment_link.readable_text
Eggs are often thought of as delicate and fragile, but this activity will show that with a simple chemical reaction we can give them a bit of bounce.

Printable downloads

Follow these steps...

Think and talk about...

What can you see happening?

Did you see any bubbles appearing?

Why do you think changing the vinegar halfway helps to speed up the process?

Investigate...

What happens if you give the egg a gentle squeeze?

How high can you drop the egg from before it breaks?

What happens if you put the naked egg into other liquids? Try putting it in water or golden syrup and see what happens.

What's the science?

The vinegar contains ethanoic acid (also known as acetic acid), which reacts with calcium carbonate in the eggshell. One product of the reaction is carbon dioxide gas, which appears as little bubbles forming on the eggshell. Over time, this chemical reaction dissolves away the hard eggshell. We are left with the thin egg membrane with the raw egg inside.

This membrane is surprisingly strong, and the egg can be dropped from a small height without damaging it: it can bounce.

The membrane is 'semipermeable': water can pass through it, but substances dissolved in the water cannot. When the egg is immersed in golden syrup, a strong sugar solution, water leaks
out of it.

Science in your world

Many marine organisms make their shells from calcium carbonate. The ocean is becoming more acidic, as carbon dioxide released from burning fossil fuels dissolves into it. The increasing acidity makes it harder for shells to form, and can even dissolve them away - a major threat to marine ecosystems.

Key Components

1. Hull:

The body of the hovercraft, usually made from lightweight materials like plastic or foam. The design should be streamlined to reduce drag.

2. Lift Fan:

A small motorized fan creates the airflow necessary for lift. When the fan spins, it pushes air downward, forming a cushion that lifts the hull off the ground.

3. Throttle Control:

A speed controller adjusts the power to the lift fan. More power increases lift, while less power decreases it.

4. Steering Mechanism:

Hovercrafts often use additional fans or rudders at the back for directional control. By varying the thrust on different sides, the craft can turn.

5. Remote Control System:

Typically includes a transmitter (held by the operator) and a receiver (inside the hovercraft) that communicates commands for movement.

How It Works

1. Lift Generation:

When the lift fan is turned on, it forces air under the hull, creating a high-pressure cushion. This cushion counteracts gravity, allowing the hovercraft to float.

2. Movement:

By varying the speed of the lift fan and using additional fans or rudders, the hovercraft can move in different directions. For instance, increasing the thrust on one side while decreasing it on the other will turn the craft.

3. Surface Interaction:

Hovercrafts can travel over various surfaces (land, water, etc.) due to their air cushion, which minimizes friction. This capability is what distinguishes them from traditional vehicles.

Principles of Operation

Bernoulli's Principle:

The lift is partially explained by Bernoulli's principle, which states that as the speed of air increases, its pressure decreases. The fast-moving air under the hull creates low pressure, helping to lift the craft.

Newton’s Third Law:

The action of the fan pushing air downwards results in an equal and opposite reaction that lifts the hovercraft upwards.

This combination of components and principles allows mini RC hovercrafts to operate efficiently and manoeuvrebility.

If you have even just some of the items we've listed, there is plenty that you can do with them! So go ahead and gather up what you can before diving in to the experiments we've compiled below.

Bicarb and Vinegar Volcano

Mix together bicarbonate of soda and vinegar in a container and watch as they react and create a fizzy eruption. Why not go the extra mile and add a few drops of red or orange food colouring to make it look like lava, or green to make it look like slime?

Dancing Raisins

Drop a few raisins into a clear glass of sparkling water or lemonade and watch them dance up and down as the bubbles attach to them and pop over and over again.

Homemade Butter

Fill an empty jam jar with double cream and shake it until it begins to separate and turns into butter. This experiment teaches children about the process of emulsion, plus, all their hard work will result in something yummy that they can have on toast or give as a homemade gift! You will also be left with buttermilk, which can be used to make pancakes with.

Cloud Dough

To make a play dough that's as soft as clouds, it really is as simple as mixing two basic ingredients together! Combining equal parts Hair Conditioner (or baby lotion if you'd prefer) with Cornflour creates the softest playdough you'll have ever felt! You can mix food colouring in if you'd like, and keep it in an air-tight container to use again and again.

Rainbow Milk

Add a few drops of food colouring to a shallow dish of milk, then dip a cotton bud coated in washing-up liquid into the milk and watch as the colours swirl and mix together.

Magnetic Cereal

Crush up a cereal like Cheerios, Shreddies or Special K and use a magnet to attract the iron in the cereal. This experiment teaches about magnetic properties, and also how Iron is included in foods like cereal to help us maintain healthy blood.

Oobleck Fun

To make oobleck, start by mixing 130g of cornflour with 120ml of water in a large mixing bowl. Mix everything together until it forms a thick, gooey consistency. If the mixture is too dry, add a bit more water. If it's too runny, add more cornflour. Once you've achieved the desired consistency, let children play with the oobleck using their hands, spoons, or other utensils. Oobleck is a fun sensory activity that will keep children entertained due to it being neither solid nor liquid (non-Newtonian is the scientific term!)

Grow your own Crystals

Pour warm water into a glass until it's about half full. Add a few spoonfuls of table salt to the water and stir until the salt dissolves. Cut a piece of string that is long enough to reach from the bottom of the glass to the top, and tie one end to a pencil or stick. Dip the free end of the string into the salt water, making sure it is completely submerged, resting the pencil or stick across the top of the glass so that the string hangs down into the water. Leave the glass in a warm, dry place and watch over the next few days as the water evaporates and salt crystals start to form on the string.

These experiments are sure to provide hours of entertainment and learning for children of all ages. Plus, they're easy to do with ingredients you already have on hand. So why not try one out today?

What better way to get kids excited about science than with an experiment straight out of a spy novel? Write a secret message using colorless ink, wait for it to dry, then use a special secret solution to reveal the message. This activity was inspired by the Berlin blue experiment in this chemistry kit. However, while that experiment uses strange sounding chemicals and warns against putting the substances down the drain, I thought it would be fun to make something similar at home using common ingredients. I experimented a bit and came up with something that works well using only water, baking soda, turmeric, and rubbing alcohol.

My kids and I have also done the lemon juice invisible ink experiment in the past. It works pretty well, but the one downside is that your really need to apply a lot of heat (like with an iron or hot plate) to get it to work. In my experience, holding the paper over a lightbulb just doesn't cut it. That means I end up being the one to reveal the message while my kids stand by and watch. The nice thing about this color-changing invisible ink experiment is that no heat is required. Instead it uses a homemade acid/base indicator to reveal the secret message.

I knew that I wanted to use a natural indicator (like red cabbage juice or turmeric) along with a basic solution. As you can see, I tried several different combinations before I found one that I was really happy with. It turns out a solution containing only baking soda and water really has a remarkable change in color when used with the turmeric/rubbing alcohol indicator. (See below for detailed instructions.)

The kids had such a great time making and reading secret messages. The best part...even the baby could reveal the message on his own, since no irons or hotplates were involved. (Though I will warn you that if you're worried about stains, maybe have them use paint brushes instead of paper towels!)

Recommended Age Range: Preschool, Kindergarten, Elementary, Middle School, High School
Time Required: ~30 minutes (including about 15 minutes to let paper dry in the middle)
Difficulty: Easy
Cost: Under $10 (much, much less in used supplies). We had everything on hand, but turmeric can be a little expensive if you have to buy more than you will use. Maybe borrow a teaspoon from a friend!
Materials:

water (1/2 cup)

baking soda (1 Tablespoon)

paper

q-tips (or a paintbrush) to apply invisible ink

rubbing alcohol (1/2 cup)

turmeric (1 teaspoon)

paper towels (or a paintbrush) to apply color-changing solution

Supplies:

measuring glass

measuring spoons

spoon for stirring

Instructions:

1. First, add 1 Tablespoon of baking soda to 1/2 cup of water.

2. Stir the baking soda into the water to make the "invisible ink".

3. Use q-tips (or paintbrushes) to draw a picture with the invisible ink on paper.

4. While you are waiting for your paper to dry, mix up your color changing-solution. First, add 1 teaspoon of turmeric to 1/2 cup of rubbing alcohol.

5. Stir the turmeric into the rubbing alcohol. (Note: The solution can stain a little bit. I used a white plastic bowl, which was not the smartest, because it was a little difficult to clean afterwards. You might want to use a glass bowl.)

6. After the paper is dry, use a paper towel (or paintbrush) to apply the color changing solution to the paper to reveal the secret message! (Note: We used paper towels, but our hands were all a little orange for a few hours afterwards, so you might want to use a paintbrush instead!)

Try mounting other objects such as aluminum, wood, prunes-yes, even prunes!-on your torsional pendulum. What are their respective magnetic properties?

There are three types of magnetism: diamagnetism, ferromagnetism, and paramagnetism. Iron is ferromagnetic, which means it's attracted to both poles of a magnet. In atoms of iron, cobalt, and nickel, the spins of electrons in one atom will align with electrons in neighboring atoms, making regions called domains that have very strong magnetization.

The third type of magnetism is paramagnetism. Atoms and molecules that have single, unpaired electrons-such as aluminum, hydrogen, lithium, and liquid oxygen-are paramagnetic. Their electrons orient in a magnetic field, causing them to be weakly attracted to both magnetic poles.

Every electron is a magnet because electrons carry charge and spin. In addition, an electron in orbit can be an electric current, turning the electron into an electromagnet.

To accurately model the behavior of ferromagnetic, diamagnetic, and paramagnetic materials requires quantum mechanics. We encourage you to research this!

The air is trapped underneath the hovercraft by a flexible 'skirt' made from material (usually nylon fabric or rubber). The fan creates a higher air pressure within the skirt allowing the vehicle to lift off the ground. Hovercraft usually float about 6" off the ground but anything up to 9" is normal for a larger craft.
