I wanted to be able to show off some neat Hot Wheels cars around my desk at home and work and also wanted to be able to hide and bring my flash drive with me places. I cut a Hot Wheels car in half and taped over the circuitry and hot glued it into the back end of the car. In the front of the car a cap was glued in. The cap was made out of cardboard but it could be a manufactured one or a homemade one out of whatever.
Flash drives apparently can go through the washer and dryer sometimes. I accidentally had this go through about three separate times and it still worked. The storage on this was around 4GB. You can get a micro form flash drive that has well over 100GB and at some point a terabyte will be the normal and at some point further perhaps even petabytes.
