Design and build a self propelled vehicle

This week I decided to build a self propelled vehicle.

I never thought it would be such a challenge for me. I spent several days building and testing and nothing worked. I was pretty frustrated, but I just didn't want to give up.

I read and looked a lot about it on the internet. At first sight, the things look really easy, but once you try them out, it doesn't work.

until I came to this vehicle:

First I made a sketch, then I looked for the materials and started to build it.

I made holes in the straws and the lids. I build everything together. The small sticks are for stability and with the rubber bands you pull the whole thing up so that it can drive - sounds simple

What you learned by doing it ?

This time I've learned a few things

In any case, don't give up so easily. I had a completely different idea in the beginning, but it didn't work at all. I tried it and tried it.

Also I learned that the wheels (the lids) should be more stable. But I searched everywhere and unfortunately I only found these types of lids. I also tried other things that you could use as wheels, but these lids still worked best.

It also depends on which rubber bands you use. I first tried it with a big and long rubber band, but then I noticed that it works better with small and thin rubber bands.
