Hooked on science: Make a Diaper Genie windbag

Friday, April 4, 2008

How many breaths of air will it take you to blow up a 6-foot-long Diaper Genie refill bag? Using Bernoulli's Principle it will only take one breath. Here's another experiment that might get you and your family hooked on science.


Diaper Genie refill


STEP 1: Remove about 6 feet of Diaper Genie refill and cut.

STEP 2: Tie a knot in one end of the Diaper Genie bag.

STEP 3: Using two fingers and two thumbs, hold open the end of the bag that is not tied.

STEP 4: Hold the bag 6 to 12 inches from your mouth and blow a stream of air into the bag.


As the stream of air from your mouth blows into the bag, it pulls more air from the atmosphere into the Diaper Genie bag, creating a super breath.
