This interested me because he was known as a fauler in math. But it was because he did not do his work nd like to be more in the lab. It is interesting because he was considered someone that affected the way we see the world. He published 4 paper that where each on a different topic. An idea he came up with was that light was not a wave but a particle. People did not believe him because 20 years later it came up to be true.

Larry Lagerstrom: Einstein's miracle year

# data[].attributes.attachment_link.description
As the year 1905 began, Albert Einstein faced life as a "failed" academic. Yet within the next twelve months, he would publish four extraordinary papers, each on a different topic, that were destined to radically transform our understanding of the universe. Larry Lagerstrom details these four groundbreaking papers.

This is interesting because it is interesting how it work. It is simple to make but really effective. I would not use this in my real life unless it is for a project but it would probably help many people around the world. It would stop them from drinking dirty water and would improve their lives.

Intro: Simple Classroom Water Filter

This instructable would be a great water filter to design with students especially those in upper elementary or middle school. The simple design of the filter will allow the user to filter out large and small particles as well as clear the water sample to some degree. I made this to show students how the different physical properties of materials can work together to form a function for everyday life. The water filter is made from everyday household items and can be constructed in a short period of time. The instructable also includes directions on how to create a water sample to be filtered. In this instructable, I am going to share my simple water filter plan, as well as some helpful hints to assist in your making process.

**Note: This is for entertainment/educational purposes only. It is not intended to be used as a water filtration system for human consumable water sources.

Step 1: Materials + Tools

Tools:

Drill and 1/4" drill bit

Scissors

Box Cutter

2 Liter Bottle (2)

Measuring Cups

Measuring Spoons

Funnel

Colander

Pan 6" X 10"

Materials:

Wash Cloth (1)

Cotton Balls (8)

Coffee Filters (4)

Small Gravel 1/2 cup

Fine Sand 2/3 cup

Charcoal 2/3 cup

Corn Starch 1 Tablespoon

Tea Granules 1 Tablespoon

Potting Soil 1 cup

Water 8 cups

Step 3:

Place a funnel into the top of the 2-liter bottle.

**Note: If the end of the funnel is too narrow, use the box blade or sharp scissors to trim off the bottom of the funnel to make the opening larger.

Step 13: Steps to Make the Filter

Drill a hole into the 2-litter bottle. (Use the empty bottle)

**Note: Place a block of wood under the bottle cap, so that you do not drill into the tabletop.

Once the hole has been drilled, screw the lid back onto the bottle.

Step 14:

Cut the empty 2-liter bottle into two pieces.

Use the box cutter to start the cut, and then use the scissors to continue cutting the bottle.

The bottom half of the bottle should be cut, so that it is 1" above the half mark. This will cause the bottom part of the bottle to be slightly longer than the top half. You do not want them to be equal in length as the top section will be placed into the bottom section and adequate spacing needs to be available.

Step 15:

Invert the top of the 2-liter bottle and place into the bottom section of the bottle.

The top portion of the bottle should be upside down with the large opening facing up.

Top Section = The Filter

Bottom Section = The Catch Bucket

Step 16:

Place 4 cotton balls into the bottom of the filter.

**Place one of the four cotton balls over the opening of the filter's lid, so that it is in the "neck" of the 2-litter bottle.

Step 18:

Take one of the wash cloth halves and fold it in half. Then place the folded wash cloth on top of the cotton balls in the filter.

Step 34:

Measure 2 cups of the premixed water sample and pour the water sample on top of the small gravel.

**Pour this gradually so that the water does not run over the top of the coffee filters.

Step 35:

Watch the water filter.

You should notice that there are no foreign particles in the filtered water, and the water has cleared considerably.

This project is a project to make a bike that is easily portable bit is still useable. It also has a Gps so that you can find it in case of anything. This would be successful because there are a lot of people that rob bikes and with a GPS, this would limit the amount of robbers of bikes. Also this would save money for the user and they would be able to locate there bike incase of anything.
