Hi, sorry for the very late reply. Just wanted to finish the first phase of the science fair then come back for more clarification and advice.
We are now planning how to do our experiment so, my group decided to use a small batteried vacuum and we're thinking of using a 12-inch hovercraft instead of the 48-inch of plywood in the procedure.
About the materials:
Is it possible to use a regular staple instead of a staple gun?
Any cheap substitute for an electric jig or a spiral saw?
Do you think it's enough to measure the type of surface on the hovercraft in five meters, or is it too short?
Thanks for the replies, we really appreciate it a lot
