In high school, some other nerds and I were selected as the most “science-oriented” kids at our school to attend a physics design competition, which consisted of competing against other school teams to build a self-propelled vehicle from a box o’ stuff (paper clips, rubber bands, paper towel dowels, styrofoam in various sizes, ballons, string, glue, etc). The vehicle that went the furthest on a course won the competition.
The only rule was no teacher participation or input. We were serious about winning. So, our little team of 5 put our heads down for a few hours, went through various designs, trashed them, re-worked them, etc until we finally agreed on something workable and finished building it with minutes to spare.
In our rush to complete it on time, we somehow built this monstrosity without realizing what it looked like until we had time to sit back and admire our work.
A penis. One with two big inflated blue ballons on one end (blue balls, for propulsion) a very phallic looking tapered body, complete with half of a small pink rubber ball glued on the front end to give it an aerodynamic profile (with a pinhole on the “head” no less, to let air flow through the shaft if it could not get around).
I was nominated to bring it on stage to demo it (and we were randomly selected to go first, no less). I had forgotten that we had to name the contraption and provide some info as to where we got the design cues and influence. Best I could come up with at the last minute was “the Phallic Flyer”, at which point the whole auditorium fell apart. Needless to say, we were not allowed to demo it after that.
Our teacher was trying to act upset…but was clearly struggling to hold back his laughter on the van ride home. He finally had to pull over and let it all out when he overhead me telling one of my friends in the back seat the sound it would have made as it flew down the stage (piiiiiiiiiissssssssssssssssssss)
