This is the rubberband car that I found. To me it looks very structured and simple. We can of course change the materials to look somewhat like the materials on here. Like instead bottle caps we could use clay.
For the original design, which can be changed, you will need two wooden screwers, two small bottle caps, two big bottle caps, two straw of any kind, hot glue gun but since we don't have access to that we'll use duct tape and/or school glue, a drill but again since we have no access to a drill we can maybe use scissors or toopicks, and lastly a rubber band.
