Fountain Connection

Try to figure this one out... a Fountain Connection looks like a Tornado Tube, yet its purpose is to make an erupting fountain instead of a swirling tornado. In fact, this fountain seems to defy both logic and the laws of nature. Use this experiment to study gravity, air pressure and partial vacuums. We use it at conferences to fool the really smart physics teachers. If you like the Tornado Tube, you'll love this one too! Recommended for children ages 6 and up.

What's included?

• Two 1-liter bottles (included with Fountain Connection kit only)

What does it teach?

Learn about gravity, air pressure, and how partial vacuums work.

Product FAQ

• What size bottles will this fit in?
  The connection fits into two 1 liter bottles but you will need to cut the tips for it to work the best.
• How does this work?
  The connection teaches a lot about partial vacuums and gravity.  To start, the water should be in the top bottle.  The water will flow down one of the straws therefore displacing the air up the other straw, both of which have tiny holes near the center.  When the air flows up the straw, it takes the water that has leaked through these little holes and pushes it upward, creating a fountain.
