5. Make a Baloon Rocket
You will need a balloon (preferably a longer one), 1 piece of kite string, 1 plastic straw, and tape for the number 5 on the list of cool experiments to do at home with household items.
Tie one end of the string to a chair or a door knob and put the other end of the string through the straw. Pull the string tight and then tie it to another support like a door knob or a chair. Now blow up the balloon and pinch the end of it while taping the balloon to the straw. Now let go and watch your rocket fly!
