Next make four holes on each side of your container that are just a little bigger than the straw thickness. Insert your straws all the way through so that they stick out both sides. These will be your wheel axles. If they do not turn easily, then pull the straws out and make the holes bigger.

3. Make the wheels! You can make wheels out of a piece of cardboard. Simply draw four circles and cut them out. You can do this by taking any circular object and tracing around the edges on your cardboard before cutting them out. I used four old instant coffee container lids that I had saved for my wheels. If you'd like to use container lids for your wheels, just save four of the same kind, then you can build your own crazy wheeled vehicle.

5. Repeat on the other side! Now repeat step four on the other wheels. Make sure to try your best to keep each wheel centered on its axle.

6.Finished! VOILÀ! A four wheeled Mars Rover! You can start rolling it around or dress it up. This is my favorite part of any project. I looked through my recycling bin and found a detergent push button top. I attached it to the top of my Rover and now it's a futuristic piece of equipment! For my windows I cut out small pieces of cardboard from a popcicle box, then covered them with some black tape and attached them. Have fun and see what you can come up with.
