Small-scale experiment

Intrigued by our epic idea, we decided to carry out a small scale experiment using a cardboard box and a desktop fan. The goal of the experiment was to find out what spacing of holes was best for the surface of the table.

We made a grid on the top surface of 1 inch squared. Then made pin holes on every inch. We then sealed the fan as best we could (we ran out of duct tape ffs) and ran the test with a CD as a puck.

Initial Results

We found that while effective, 1 inch squared was not enough to provide lift to the puck. Results were dramatically improved when we added half inch diagonal holes. On a side note we found that blocking off the central hole of the disc increased the lift dramatically.

We then moved onto the designing the table, but that's for the next post...
