Balloon Rockets

Math & Sciences

2.5–6 years

Blast-off! Balloon rockets offer a wonderful hands-on opportunity to learn about important science concepts, such as energy, thrust, trajectory, and velocity. 


  • Balloons 
  • String (about 5 metres) 
  • Drinking straw 
  • Sticky tape 
  • Clothespin 
  • Coloured pens (optional) 


  1. Thread the string through the straw. 
  2. Tie each end of the string to a safe support structure in the room (eg. two chairs, door knobs, etc.)
      1. Blow up the balloon and pinch the opening with the clothespin (don’t tie it). 
        1. Tape the balloon to the straw with sticky tape, use 2 pieces of tape to ensure the balloon is thoroughly secured. 

         Ready for lift-off 

        1. Perform a countdown and release the clothespin, watch as the balloon rockets across the room.
        2. Inflate and repeat as many times as you’d like; try experimenting with different volumes of air. 
        3. You can also decorate your balloon rocket by drawing pictures on it. 

        Increase the Fun

        Add some healthy competition by making multiple balloon rockets and invite family and friends for a balloon rocket race. 

        How does it work?

        As the air rushes out of the balloon, it creates a forward motion called ‘thrust’. Thrust is a pushing force created by energy. Thrust comes from the energy of the balloon forcing the air out. Different sizes and shapes of balloon will create more or less thrust. 

        At Learning Jungle, we believe all children are capable, confident and full of potential. Co-learning empowers your child to take initiative. Encouraging child participation and engaging in open-ended, thought-provoking conversation throughout play is important for healthy child development.

        Conversations with your child

        • How far do you think the balloon will travel? 
        • Should we try using more/less air this time? 
        • What do you think makes the balloon move? 
        • Can you try blowing the balloon up? 
        • Would you like to decorate your balloon rocket?
