The farthest we got was 78 ft. It was fun doing this.

If you stretch a rubber band between your fingers, you’ll feel a pull – that’s the force that the rubber band uses on the rocket. The more you pull the rubber band, the harder it will pull the rocket forward into flight. Depending on how strong you are, you may or may not be able to throw it as strongly as the rubber band. Does that help?

Please explain in terms my 8 & 5-yr old can understand – why does it go farther with the rubber band than when you throw it with your hand? thanks

Oh, wow – how cool. I love it when those happen. I just sunk my rocket into the ground also, but that’s because it shot over 1,000 feet high and didn’t pop the nosecone (I think I packed it on too tight)! Oh, well, back to the drawing board… it’s part of the new “Unit 20: Aeronautics” I am working on, but more on that later. I know you’ll get the 75′ mark with this one – try chaining your rubber bands?

They worked so well and our first sunk into the ground a good inch upon landing! (soft ground after rain) Ours are flying well over 40 feet but not quite 75′…yet!

Make sure you are logged in first…

What happens when you try a different computer?

Try it! And then let me know how it goes… and send me a picture of your invention!

I wonder. Would it work as a “Paper Airplane Rocket Car” (P.A.R./C.)? Would that work? It would also be fun if the P.A.R./C. would start rolling, and then go airborn, similar to how a plane starts to take off. That would be cool. Maybe if it was attached to the pop rocket……:)

It worked! Thanks for the tip.

It really worked! The tape really worked! Thanks a lot.

Andrew,

Our kids used some tape to hold the folds together, and found that it flew better that way. What worked for you?

By: Aurora

Hi Andrew! Try it and see…you should be okay depending on where you put it.

Just in the blue, using the : and D together make the symbol . Have fun using it.

I am not writing as Laura. I am her 10 year old son, Andrew. I think your experiments are fun & easy, but this was VERY EASY . I have a question: can we use tape on our rocket? Will it affect the way the rocket goes?

Having SO MUCH FUN with this one!! One’s stuck in the tree outside the front door. We’re going to try some modifications and see what we can come up with. Photos and videos to follow. Thanks, Aurora!!

Hi! I asked my son what would make it go farther and after some thinking, he said, “A bigger rubber band.” So I pulled a giant rubber band out of my pocket (the kind they use in the produce section), he laughed, and it goes so high it’s almost hard to see it. Of course, it then comes STRAIGHT down so watch out!!

I suggest only flying these things UP, as they go FAR and have a pointy tip, but you can’t measure height very easily (the protrator-straw-string height gauge is best for objects that don’t move). So, clear the area and fire horizontally to get your measurement.

“Hey, this is 15 year old Caleb. Me and my brothers just did this and i think we broke the record for how far this rocket goes. i measured it out and we shot one exactly 100 feet, and that was with a decent wind from the left.”

WOW! Awesome! Can you post a photo of you and your invention? We’re putting up the new photo site now…

This slingshot was fun and easy to make. My first launch was 30ft.

My sons tried a three-man launch with a cut open rubberband. I think we could rival the record height, but it wasn’t a single man launch. Try it!

Hi Aurora,
Thanks so much for this wonderful opportunity! My kids have been begging me for a science camp! I haven’t even told them yet. I’m just going to surprise them with it. I can’t wait. The first (You Tube) video worked for us. I couldn’t get the second one to play.
Blessings…Connie

Hi! My son is very excited about the science camp!! This is agreat idea!! The Windows Media Player 9 works best on our computer. Thanks again!! Tina Smith
