More rockets

We're a little obsessed over here with things that fly, especially if we can make them fly.

Making science out of straw rockets is super easy (and inexpensive) especially when you are given wrapped straws.  It does get pretty messy and can be considered wasteful.

We stopped by our favorite toy store after J's recent haircut.  I went on a search to find the coolest science-y toy under $5.  We found Squeeze Rockets.  The theory is the same as the straw rockets.  The air (this time from squeezing the bulb) pushes against the foam piece, causing it to fly off in the air!

Things to try:
*Squeeze hard and then squeeze soft.  What happens after the different types of squeezes?
*Squeeze the bulb, then place the rocket on.  Can you make the rocket fly off when that happens?
*Aim for objects (I don't recommend shooting at people).  Projectile Motion = FUN Science.
*Shoot the rocket towards a fan.  What happens?
*Shoot the rocket from behind a fan (into the jet stream).  What happens?

Hopefully, when things settle down around here, I can find some ways to make these type of launchers at home.  A quick search suggested 20 oz soda bottles as the launcher.  I was hoping for something more handheld, but I'll have to give it a try in the near future.
