Balloon Rocket.
Difficulty: Easy
Time: Less than 10 minutes This is a very easy experiment to show the rules of force through a balloon acting like a rocket! You may need a friend or adult for an extra pair of hands. Watch the tutorial video below to hear a lesson on the science behind this experiment, and how to go about doing it! |
WHAT YOU WILL NEED:
METHOD:
STEP 1: First, thread the string through the straw.
STEP 2: Next, either hook your piece of string across a large archway using the two hooks, or rig it up between two chairs.
Tip: It works best if one end of the string is higher than the other.
STEP 3: Blow up the balloon but don't tie it off, just hold it pinched shut.
STEP 4: Without letting the balloon deflate, tape it to the straw on the string.
STEP 5: Slide the straw and balloon up to the high end of the string.
STEP 6: Let go and watch your balloon rocket shoot to the end of the string.
- a balloon
- a piece of string (3 metres long)
- a drinking straw (straight not bendy)
- Masking tape
- 2 stick on hooks (optional)
- two heavy things e.g. a door or a chair
