This one is so easy but so very entertaining! All you need is a balloon and a hex nut! Squeeze the hex nut in the balloon and blow up the balloon.
Now holding the balloon, I start swirling the balloon. If you do not hold onto the balloon firmly, this is what happens!!
Oops! Clumsy me! That balloon was camera shy.
Now holding the balloon firmly, I began, once again, to turn the balloon in a swirling motion.
It is making kind of a screaming sound! That is the sound of all of the little corners of the hex nut rapidly hitting the side of the balloon! Cool, right?
The end of day four is here. Tomorrow is our last day! We will finish with a grand finale! In the morning I will be doing an experiment, then the finale. Nine experiments down, two to go.
