Ever wanted your toy cars to really go? Wanna new way to race? Want an excuse to build something really cool for your kid? Or do a fun project WITH your kid? You don't have to go buy a new cheap plastic toy, make your own fun from leftovers from prior projects!

This is a not too complicated project that easily modified to use materials you have on hand. For ours we used scrap wood, scrap plastic, and a rubber band from an asparagus bunch! It does require basic carpentry skills, but nothing too usual or complex. You'll notice there are a lot of steps in this instructable, that's mostly because I was trying to be thorough, so don't let it scare you.

This prototype is a single car launcher, but could easily be modified to launch 2 cars at once for racing purposes... that will probably be the next project! It also is designed so that you can attach it to your hot wheels tracks (not shown here).

Hope you enjoy!


Step 1: Materials

Most of this was just scrounged around our basement. After reading through the instructions, feel free to attempt substitutions if needed.

You'll need:

A few Hot Wheels, Matchbox, or similar cars to ensure size and for testing.
Block of wood, taller/longer than your cars.
Short screws (4 top, 4 bottom, 6 sides)
4 finishing washers (optional)
I eye screw
Scrap plastic as wide as your wood block, and a few inches longer (or stiff cardboard, or thin wood, or even an old circuit board!)
Scrap clear stiff plastic (either recycled from some packaging, or lexan, or even shrinky dink material) about the size of your wood block.
Rubber bands (at least one, various sizes are nice) We used one from some asparagus.
String or twine (optional)
"Bumpers" (little rubber/plastic feet) for the bottom (see step 11)

Hardware requirements:
Saw for cutting the wood
Dremel or Drill
Business cards or other similar scrap cardstock (try junkmail!)
Utility knife
Straight edge
Sharpie/marker (for marking plastic)

<p>Great instructable. I made my own version, with cheaper materials and a trigger:<br></p><p>https://www.instructables.com/id/Cheap-and-Easy-Catapult-for-Hot-Wheels-Style-Toy-C/</p>
Awsome job! Love it. Glad to be of inspiration!
Thanks!! :-)
Good job, that's neat!
<p>so cool me and my son going to build this tonight thanks</p>
you stole that from kipkay!!! :@
Ah, just did a little googling, and apparently you're accusing me of ripping off my own design. The Make Magazine video, with kipkay, is of him demonstrating how to build this design, which was published in the kids issue of Make last year. Which I wrote. So dude, perhaps you should do your research before accusations of theft.
I'm sorry, but I would hardly be surprised if someone else out there has thought of using rubber band power to launch a hotwheels car. It's not exactly a complex concept. For the record, the concept for the design was mine, for the rubber band contest in 4/09 here on instructables. The design was my husband's, and all the photos and instructions are done by me. I wrote an article for Make Magazine, published in Dec of last year, on how to build one yourself.
&nbsp;I notice that an adult is holding the launcher as the child pulls the band back. Why not put a handle on top so that one person can easily launch the cars?
That was mostly because our child was a little young for doing it by himself at the time (age 3).&nbsp; Now he's 4 and can do it himself.&nbsp; Also we've added the track connector now (see this month's issue of MAKE magazine) and he works that fine by himself. <br /> <br /> But a handle is a good idea!<br />
Does this hurt the car in any way shape or form.
Can't see how it would. unless you shot the car into something, same as if you threw it.
i like it! good work!
This is very cool. The clear plastic could be just a hunk of wood, or even pegboard - but the Lexan lets the kid see and anticipate the launch action. Gets my VOTE.
