One common problem with this part is that if the rubber band is touching the front axle before being hooked to the front of the tube, it will rub and ...
This is an easy to make rubberband car using a paper towel tube for the body. I've made these cars with groups of kids at Library programs several times and it's always lots of fun. You’ll need a paper towel tube, two old CDs, a couple of pencils, one jumbo paperclip, about 5 rubberbands (these MUST be #14 size! it won’t work nearly as well, if at all, with fatter or thinner rubberbands), lots of masking tape, scissors, a ruler, a single-hole punch, and some corrugated cardboard for front wheels.
Step 1: Punch holes for axles
Use the hole punch to make holes for the axles, two straight across from each other on either end. It helps the car roll better if the wheel holes are lined up and square with each other, front to back and side to side. Using a ruler to draw a line down the side of the tube can make it easier to line up the holes.
