Fast – Rubber Band Car (Weekly Unplugged Project)

By , July 12, 2009 9:29 pm

The theme for this week’s Unplugged Project was fast.  This is a fast post because the week went really fast, and we will soon be flying in a fast airplane to France.

We did experiment with some rubber band powered cars, and finally succeeded in making an original prototype from a Knex Set that went very fast…for about 6 inches.  I think the axle needs work, as does the length of the rubber band.  It was fun, even though our model obviously needs improvements.

If you have budding engineers at your house, try this project and see what you can come up with!

Here are a few links to get you started:

LEGO Rubber Band Car


If you did a fast-themed Unplugged Project this week then please link to your post below (not just your blog, we always want to be able to find your fast post).  If you didn’t do a fast project, then don’t link, but please read more about how to join in the Unplugged Project here.  We’d love to have you!


Since I will be away until August 6th, the Unplugged Project will be on vacation also (although, if anyone is interested,  I hope to post a few virtual postcards from France, perhaps even one a day if I can!).

The next Unplugged Project will be Monday August 10th and the theme will be:


I bet we’ll have a lot of photos by the time we get home, and you’ll have a lot of time to think about what you will do with your photos!

Enjoy and have fun!

    Good fun. We used to make rubber band ‘cars’ out of large tins when I was a kid.

    We don’t have a blog, but I’ve decided to start doing the unplugged project and writing a note about it in the comments, if that’s ok.

    For fast, we’ve done something I’ve been planning for years – made a car race board game as a gift for my father-in-law, who’s a Formula 1 fanatic. It’s not completely finished, yet, but I’ve designed the pieces, which can be used like a train set to make lots of different tracks, and I have planned the rules. We need to have a play with it with some friends on the weekend to test them. I downloaded some pictures of racing cars for my 2yo to colour in. We’ll use them to print the rules on the back of, and to decorate the box.

  2. Hmmm, not sure where Mr. Linky is…. I’m a little late this week, plus my project is more of a tip.
    Have a great trip!

    What a great idea for a game! Definitely goes with “fast” too. Thanks so much for joining in and welcome to the “Unplugged Project.” Leaving your ideas in a comment would be a wonderful way to join us. I look forward to hearing more of your ideas when the “Unplugged Project” resumes in August!

  4. I didn’t see Mr. Linky either, but we did make a little rubber band boat out of an Altoids tin this week. It was fast to make, and fast in the water too.

    Thanks for the inspiration!
