It may seem like magic as an eye dropper floats and sinks on your command in a bottle of water, but it's science...and now the whole class can make one for about 50 cents each! Are you teaching about air and water pressure? Maybe density? The Cartesian diversions class kit is a great way for students to learn about concepts hands-on! We give you enough supplies to make enough to make 60 divers! Your students will love creatively decorating their divers while learning all about what makes them tick!

Each kit comes with:

• 60 ballast nuts, 60 pipets
• 1 Fizz-Keeper Pump
• 1 sheet of acetate
• 2 ft. of coated copper wire
• 5 pipe cleaners
• 3 permanent markers
• 4 ft of fishing line
• 3 sheets of colored craft foam
• 2 ft. of yarn

You will just need to supply a platsic water or soda bottle for each diver. For ages 8 and up.
