This is the kind of thing I wish I had back in grade school. I could have launched these across the room without anyone being the wiser. Be sure to fold the nose down securely, or you’ll have air leaks (and no launch!) This is a smaller version of the Rocketships experiment.


All you need is a

  • sheet of paper

  1. Whoa… that’s awesome!!! 🙂

    My new record is 97 feet! My mom made a rocket that went that far just now!

  3. Elaina Raffensperger-Schill says:

    I just spent two hours readjusting and measuring one of these and two of the slingshot rockets. Our farthest for this one was 19 ft. 10 in!!! For the slingshot rockets we used a really fat rubber band and I got 931 inches, which is about 78 feet!

    HK- my large fins made my rocket work like a parachute. Really fun!

    Love the trick rolling up paper- huge help when no smaller straw available!

    Fun, fun, fun! We made these 2 weeks ago and my boys (8 & 5) STILL use them and show them off to anyone who comes over. We covered the living room with lines of masking tape at 1-foot increments and did a measuring activity, keeping track of how far they could go (the record was 10.5 ft). I’d planned to have them alter the rockets (remove the fins, for example) and compare, but we didn’t get to it. Thanks for a great – and very simple – activity!

  8. That’s a great idea! Thanks for sharing! I’ve used the stick-on divider tabs, but they usually rip right off.

    I run a science enrichment program and have now made 100’s of these rockets . I have a different trick for the fins. I use POST ITS All different colors… add the sticky tape along the straw. Then fold down to make the fins. There will be a little excess along the bottom but it is fine. I then add tape in between the fins. Works great even 5 year olds can build their own rockets without using hot glue.

  10. Haha! That’s wonderful! Had no idea blowing rockets could benefit speech… yet another great reason to do your science homework! 🙂

    BTW, the speech therapist was very happy that my boys are blowing rockets, it is a great mouth exercise!

  12. Laura Rosales-Dills says:

    They were fun, but we made a mistake: we made the rocket on the SMALLER STRAW, NOT THE BIGGER STRAW! But once we fixed that, there was no problem. 🙂

  13. Jennifer Wright says:

    This was literally HOURS of fun for my 11 & 5 year old boys and me! We made rockets and designed several different types. Some only flew a couple of feet others made it about 18′. I believe our lungs got a good work out. For added excitement, we got out the bike pump and rigged a straw on it to launch our rockets straight up into the air.

    My children, ages 3,6, and 8 loved this! It was super easy and it worked!
