Introduction: Long Distance Mousetrap Car

Picture of Long Distance Mousetrap Car

This is my guide on how to build a mousetrap car that is meant to travel long distances. Remember that this is just a guide, so if you have any ideas that you want to try feel free. Overall this cost about $25 and takes 3 to 4 hours to complete, but most of that time is waiting for glue to dry.

Step 1: Materials

Picture of Materials

Here is the list of items I used to build my car with the quantities in parentheses. These can all be bought at Wal-mart
- 1/4" rubber/faucet washers (4)
- CDs (4) I bought a 5-pack.
- Duct Tape
- Jumbo craft sticks (75-pack)
- Mouse trap (2) I bought a 4-pack
- Scissors
- Straw (1)
- String (Smallest size you can find)
- Super glue
- Wood Glue
- Wooden dowels 3/16" (2) I bought an 8-pack
- (Optional) Small balloons

Step 2:

Picture of

Using the wood glue; Glue two mouse traps together. The front is where the metal trap is and the back side is the big, red V. 

Caution: Mousetraps are dangerous, handle with care.

Step 3:

Picture of

Glue five craft sticks on the bottom of the mouse traps starting at the back.

Step 4:

Picture of

Flip back over and glue a craft stick on each side of the mouse trap while leaving the width of one stick on the back side.

Step 5:

Picture of

Flip back over and glue craft sticks so they line up with the two on the top. Leave ½ to 1 inch hanging over the front.

Step 6:

Picture of

Cut the top, front stick so only an inch sticks out making it level with the stick below it. Cut a craft stick into fourths and use the ends to fill in the space between the two sticks.

Step 7:

Picture of

On the back side, Glue the craft sticks so they are three sticks thick while two more sticks are added to the length. Start by placing a stick at the end of the stick already attached to the mouse traps. Then put a stick on top so it over laps both of the sticks below. Add another stick on top the overlaps both below. These steps are numbered in the picture. Repeat this process again to get the required length. Repeat on the other side.

Step 8:

Picture of

Add Cross sections where necessary to hold the body together. I added two with a V like one at the end. The reason for this is because it would be close to where the axle would be and I didn't want my string to rub against anything. I also put one of my supports on top and bottom while I put the other on bottom. I then glued three sticks together and used that to connect my supports. I used scissors to cut the end of two craft sticks into V shapes and glued those on the bottom of the three stick thick support and to the bottom of the two body sticks.

Step 9:

Picture of

Cut the sticks in the back so the one that stick out the farthest matches the one below it.

Step 10:

Picture of

Take a wooden dowel and glue it to a craft stick. Then put duct tape on the back of the stick making sure that it isn't thicker than the metal bar of the trap and attach it to the mouse traps. It may be helpful to use a stick to prop the trap open. If you take off the spring part you will run into the problem of putting it back on after the tape is on.

Step 11:

Picture of

Cut the straw into fourths. Glue these near the end of the sticks and cut the straw so it doesn't hang over the edge. On the back make sure that the straws line up with the end of the wooden dowel that is attached to the traps. You may also want to put duct tape over the straws for the added strength.

Step 12:

Picture of

Now we have to put wheels on it. Glue the rubber/faucet washers in the hole on the CD using super glue. Once again it may help to add duct tape on the outside over the washer. If you have a balloon try to fit it around the CD and then but off anything that isn't around the edge of the CD

Step 13:

Picture of

Take two of the wooden dowels and cut them so they are an inch or two longer than the widest point of the car. Then you can take the dowel and slide it into the washer if it doesn't fit scrape off some of the edge with the scissors as shown. You may want to add a little super glue on the end of the dowel, but if you do remember that once it is on it doesn't come off. I found that the washers grip the dowel well enough to not need the glue.

Step 14:

Picture of

Slide the open end of the dowel through the two straw pieces and then attach the other CD. Do this to both the front and back.

Step 15:

Picture of

Take the scissors and make a notch on the end of the dowel for the string to catch on. Cut off the string so it reaches from the back axle to the end of the dowel when it is all the way forward. Tie one end of the string in a slip-knot. Slip the knot over the dowel and tighten it while making sure it is over the notch. Then wrap duct tape around it to keep it in place.

Step 16:

Picture of

Now everything is built and it's time to test it. Wind the string around the axle while making sure the string overlaps a few times then just turn the axle and it will wind the string the rest of the way. Set it down in a long, open area and let go of the axle and see how far it goes

Is it possible to do this with one mouse trap and it still to move? Im doing a project for my class and we are only allowed to have ONE mouse trap. Please answer its due on Thursday, and I'm pretty desperate!!!:o THANKS to ANYONE who answers!!!!!

COOLERTHANYOUX2 (author)ShelbyS2016-01-07

Yes you could just center the mouse trap.

How did you set it off? We made the contraption, but we can't set it off successfully

Help please

ChrissyM3 (author)Cmicks82015-11-22

Hi - Did you set the trap? The spring has to be loaded before you wind the string around the back axle...

Good luc!

We made this for our son simple machine science project. He had alot of fun making it. The instructions were fairly easy to follow but, I had to help with some of it.
