Shar Fletcher asked "Do you think there is anyway you could make a rubber band powered car that is about 20 inches long (has to be less than 25 inches long) and is able to push 500g masses out of the way (highest mass is 500 grams). It is for a project and I'm really stuck! " I have already done a car for a similar task and the link is below but today I made a different one using a letter tray from my local bargain store. This car is only about 14 inches long. A longer car would allow more rubber bands to be used for more power but I didn't need any more for the task. Main Components - * Plastic letter tray for the chassis * Metal tube (from bargain store garden department tomato trellis) * CDs/DVDs for wheels - I have run out of CDs today so I had to use wheels cut from plywood but I would suggest using 5 or 6 CDs together for each of the back wheels to give a good wide wheel and add a rubber tyre strip cut from a rubber washing-up glove. You only need 1 CD for each front wheel as grip is not important at the front * You may need plastic bottle tops for hubs for the CDs (see this helpfile for doing this http://youtu.be/ZRrjBuWfmrM) I used CDs that already used a different option. * Pen tops or plastic tubes for spacer to keep wheels away from chassis * Rubber bands * Hot glue Main Tools - Hot Glue Gun Drill and suitable selection of drill bits Here is another of my cars pushing 500 grams https://youtu.be/CRnH7grNJW4 Carrying Dropping Pushing Pulling Stopping https://www.youtube.com/playlist?list=PLA5a2xPRSrB04L6RpUAs5akmK3jqmahPL Bargain Store Projects http://www.youtube.com/playlist?list=PLA5a2xPRSrB0ZqYUdxXaQaJdg-cs3dKIi Rubber Band Power http://www.youtube.com/playlist?list=PLA5a2xPRSrB1otXh0w36OwsYIHZznUWp6 Rubber Band Powered Car #8 http://www.youtube.com/playlist?list=PLA5a2xPRSrB0zJ5RHjvsw46Mio6uJjF5_ Rubber Band Power Cars https://www.youtube.com/playlist?list=PLA5a2xPRSrB3g5RiX8Kf_uUBOL0Tb7AS0 Rubber Band Power Planes https://www.youtube.com/playlist?list=PLA5a2xPRSrB1iBkfCc2jzfTK6LA9Sh7vi I cannot answer comments from people who have blocked replies, so if you don't get a reply to your question that may be the reason.

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. https://www.youtube.com/user/GrandadIsAnOldMan
