Let's carry 4 lbs over 3 m using 8 design

I have been asked if my car can weigh 4 lbs and travel 3 m. It was not designed for this task, but I tried it anyway and was pleased to find it managed quite easily once I had increased the number of rubber bands providing the power. With double the original number of rubber bands it covered the distance. I am confident I could double the power again and cover the distance much quicker but I have only done the minimum for the task set.

OK, I enjoy them too. If anybody else likes them, that is a bonus. I like to keep my work as simple and basic as possible so that it can be copied easily and improved by anybody who wants to try themselves. I recycle or repurpose items rather than buy new and when I do buy I like to keep it cheap. /user/GrandadIsAnOldMan
