Balloon Rockets

I know, I know, you'd have thought we'd had enough of balloons and rockets, but well... no :-D This activity was easy and quick to set up, and major fun. Both Bubble and Squeak thought the noise the balloon made when we let it go and the way it shot down the string were HILARIOUS, there were lots of giggles in our house today.

Other Ideas: Why not run two or more lines across the room and have races? I think this would be lots of fun for a classroom or party activity.


* thin elastic (could also use wool, string, twine etc)
* drinking straw
* scissors
* sticky tape
* balloon
* our paper rocket from our Rocket Straws activity
(this isn't necessary, we just thought it would be cool to add a rocket :-D)

On the underside of our rocket we taped a drinking straw that had been cut in half.

Then threaded our straw onto one end of the elastic.
If you are not using a rocket just thread your half straw onto whatever you are using (elastic, string, wool etc..).

Tie your elastic/string across the room, making the straw/rocket end slightly higher than the other end.

We used a kitchen chair to secure one end and tied the other to Squeak's highchair.

Tape a loop of tape to the underside of your straw/rocket (so that there is a sticky side facing out)

Blow up a balloon and while holding the end so it doesn't deflate press the top of it against the tape underneath the straw/rocket so that it sticks. Make sure the back of the balloon is facing backwards as shown in the photo.

Have a countdown and let your balloon go - your rocket will shoot to the other end of the string faster than lightning (well, not really, but pretty fast :-D).

One of our rocket balloons at the end of the line.


  1. Balloon rockets are so much fun! I have to do this with my boys soon - we have 2 birthday parties this weekend, so maybe we'll have some extra balloons ...

  2. this looks like so much fun...unfortunately we couldn't get the rocket to fly. the balloon just deflated and rocket spun. think i might have to try some other type of string...we used wool. will definitely try again. thanks for the cool idea!!

  3. We did this the other day at MOTAT, a museum here for flight and so forth. It was a lot of fun, and the kids loved it.

  4. I did this with my 3 1/2 year old son tonight and he loved it. It was so simple and a lot of fun! Thank you!

  5. We learned about flying today at scouts, and then "flew" our rockets. The boys loved it, and had a great time! Thanks!
