OM 5 Science has us learning about astronomy. In our study of early, practical applications of astronomy by the Egyptians, we learned about sundials. One assignment required Thing 3 to make a sundial and try to tell time with it, checking himself against a clock. It was difficult at first, but he got pretty good at it fairly quickly.

We made this very simple yet effective sundial by placing a pencil in a ball of clay. Every hour, Thing 3 went out and marked the hour with a stone. This sundial goes from 9 a.m. to 4 p.m. Easy cheesy! And fun!

Can you make a glittler tornado with only one bottle? With a little muscle and centripetal force you can!

Make your own bottled cyclone with this fun and easy science experiment. Watch our demonstration video, gather your materials, and print out our instruction sheet to get started. Then, explore how and why the vortex is made with our easy to understand explanation of how the experiment works below.

Tornado Science Experiment Video

Tornado in a Bottle Science Experiment Video

Supplies Needed

Empty Glass Bottle with Lid

3-4 tablespoons Glitter (the more glitter the better!)

Funnel

Water

Experiment Instructions

Step 1 - Use the funnel to put 3-4 tablespoons of glitter in an empty glass jar.

Helpful Tip: The more glitter you use, the better you will be able to see the tornado. And after all, you can never have too much glitter, right?

Step 2 - Next, fill the jar about 3/4 full of water.

Step 3 - Put the lid back on the jar and make sure it is really tight.

Step 4 - Turn the bottle upside down and quickly move the bottle in a circular motion for 10-15 seconds.

Step 5 - Finally, set the bottle down on the table and observe the tornado that has formed.

Tip: It will take some practice to get the tornado to show up as much as the one in the picture above. But even with a little shaking, a child should be able to get the water and glitter to spin around in the bottle.

How Does the Experiment Work?

When you spin the bottle in a circular motion it creates a water vortex that looks like a tornado. The water spins around the center of the vortex because of centripetal force. Centripetal force is any force that causes an object (in this case water) to move in a circular path.

Because there is glitter in the water you can see the spinning water more clearly. The glitter is similar to the dust and debris that are found spinning in an actual tornado.

I hope you enjoyed the experiment. Here are some printable instructions:

You've seen Steve Spangler use blow dryers or industrial-sized blowers to levitate ping pong balls, beach balls, and send toilet paper flying through the air. You can replicate this levitating object phenomenon on a smaller scale using objects that are right in your home! The Floating Ping Pong Ball trick uses amazing principles of air that are sure to amaze anyone, from your science teacher, to your parents, to your neighbors!

Experiment

How Does It Work

The Floating Ping Pong Ball is a wonderful example of Bernoulli's Principle, the same principle that allows heavier-than-air objects, like airplanes, to fly.

Bernoulli, an 18th century Swiss mathematician, discovered something quite unusual about moving air. He found that the faster air flows over the surface of something, the less the air pushes on that surface. That means that the air pressure on the object is lower than average.

The air from the straw, as you blow through it, produces the levitating ball phenomenon using Bernoulli's Principle. The fast air moving that you are blowing around the sides of the ball is at a lower pressure than the surrounding, stationary air. If you look closely, you'll see that the ball wobbles while it is levitating in midair. The ball is attempting to leave the area of low pressure, but the higher air pressure surrounding it forces it back into the low pressure area.

Take It Further

Are there any other objects that you can make float using the apparatus that you've created?

Science Fair Connection

Demonstrating a floating ping pong ball is pretty cool, but it isn't a science fair project. You can create a science fair project by identifying a variable, or something that changes, in this experiment. Let's take a look at some of the variable options that might work.

Try changing the length or diameter of the straw. Does it affect how hard you have to blow in order to make the ping pong ball rise? What about how high the ping pong ball rises?

Try different sizes of bottles. How does the size affect the levitation of the ball?

That's just a couple of ideas, but you aren't limited to those! Try coming up with different ideas of variables and give them a try. Remember, you can only change one thing at a time. If you are testing different straw diameters, make sure that the other factors are remaining the same.

You will need

A dry plastic comb
An indoor faucet
A head full of clean dry hair.

What to do

1. Turn on the faucet and slowly turn down the water until you have a VERY thin stream of water flowing.

2. Take the plastic comb and brush it through your hair ten times.

3. Now slowly bring the comb close the the flowing water, (without actually touching the water) If all goes well, the stream of water should bend towards the comb! Magic you ask? Not really.

How does it work?

When you brushed that comb through your hair, tiny parts of the atoms in your hair, called ELECTRONS, collected on the comb. These electrons have a NEGATIVE charge. Remember that, its important. Now that the comb has a negative charge, it is attracted to things that have a POSITIVE charge. It is similar to the way some magnets are attracted to certain metals.

When you bring the negatively charged comb near the faucet it is attracted to the POSITIVE force of the water. The attraction is strong enough to actually pull the water towards the comb as it is flowing! If you want to try another experiment with your comb, tear up pieces of tissue until they are as a small as you can get them...I mean really small! Then charge your comb again by brushing it through your hair, and bring it close to the tiny pieces of tissue. If the pieces are small enough they will jump off the table to the comb the same way that the water was pulled to the comb.It is all thanks to the wonders of static electricity.

MAKE IT AN EXPERIMENT

The project above is a DEMONSTRATION. To make it a true experiment, you can try to answer these questions:

1. Does water temperature affect how much the water bends?
2. Does the size of the comb affect the static power?
3. Does the amount of moisture in that air affect the static power? Try it after someone has taken a shower in the room.
4. Does the material that the comb is made of affect the static power?
