Hubba Bubba Blow Your Bubble

We did an awesome activity tonight using bubble gum and statistics! Kids will love this activity!

First we formulated a question " What gum blows the most bubbles in two minutes?"
Next, we stated our hypothesis "Bubble Yum will produce more bubbles in two minutes"
Independent Variables: Bubble Yum and Hubba Bubba Max
Dependent Variables: Amount of bubbles blown in two minutes

And now the fun starts!

1. Chew a piece of gum for 1.5 minutes
2. Blow bubbles for 2 minutes
3. Tally amount of bubbles
4. Average the bubble amounts

And.... The... Winner... Is...
Hubba Bubba Max!

I believe that this bubble gum blew more bubbles because it has a liquid center which makes the gum thinner and smoother.  I believe that it is easier to blow bubbles with thinner gum than thicker. What do you think? I'm only guessing here! Tell me your ideas!
