Mini blog post #1


For my first mini project i blew up a balloon and let the air out. But while letting the air out i hold two side of the balloon. Creating a rippling noise with the air.

For this project you'll need:
1. a balloon
2. air
3. a pair of hands :)

To do:
Take the balloon and fill it with air. Then slowly release the air with your hands. But while releasing the air pull the balloon elastic out to the side and slowly release, creating a rippling noise.
science?
the science in the project deals with surface area. The tighter the balloon is srteched the more noise it makes. less surface area less noise, more s.a more noise. These concepts are directly related.
