Balloon Propeller (Newtons Third Law) Sir Isaac Newton's Third Law of motion says that for every action, there is an equal and opposite reaction. Using everyday materials, your kids can see this concept come to life!
FUN Science Idea~ To help young physicists understand that for every action, there is an equal and opposite reaction you'll need these items: flexible straw, ruler, straight pin, marker, round balloon, masking tape, and pencil with eraser. Great way to teach air pressure and thrust!

Balloon Rocket Lab
Balloon Rocket! "So what’s the big deal about this lab, it seems almost grade school level? First off, again, almost none of my students have ever built a balloon rocket. This never ceases to amaze me. Second, it’s deceptively challenging. Lastly, the kids actually get the principles because of this activity."
