Hello everyone. Today in science, we conducted an experiment called Balloon Rockets. This experiment was both fun and interesting as we learned about different strategies. In this blog post, I will share the aim, equipment, method, results, and include a picture along with a video so you can try this experiment. I hope you find this blog post enjoyable and feel inspired to try it at home. It’s a lot of fun!

 

Balloon Rockets

Aim:  

• To understand the forces acting on a balloon rocket.

 

Equipment:  

• 1 balloon (round balloons work, but the longer “airship” balloons work best)
• 1 long piece of kite string (about 10-15 feet long)
• 1 plastic straw
• Tape

 

Method:  

1. Tie one end of the string to a chair, doorknob, or any other support.

2. Put the other end of the string through the straw.

3. Pull the string tight and tie it to another support in the room.

4. Inflate the balloon (but do not tie it). Pinch the end of the balloon and tape it to the straw. Now you’re ready to launch!

5. Let go and watch the rocket fly!

 

Results:  

My group set up the activity on chairs, carefully following the steps. Unfortunately, the rocket didn’t move from its spot at first. We experimented with different chair angles and balloon sizes. After much trial and error, we finally managed to get it to move halfway. Despite not achieving our original goal, we experienced a sense of satisfaction in our efforts and teamwork.

 

Picture:

Our piece of straw was short, but if you have a long straw, it will probably work best.

I hope you enjoy this experiment as much as we did.

Bye,
