This Friday night, at Greencastle’s First Friday, we’ll be trying something new, letting folks carve a foam block into a car, then propel them down a wire on Franklin Street.

For the first attempts we’re keeping it simple, although admittedly we’ve got bigger plans. For Friday night we’ve built a platform to put the foam block on, participants can carve the block into a car body, then will launch it down a cable using a CO2 cartridge.

In the future we’re going to try 3D printed and laser-cut wheels & want to also try using model rocket engines for propulsion. We’ve even thought about dual tracks for racing and putting an on-board micro:bit to measure speed and acceleration. Come join us on Friday night from 6-8 pm on Franklin Street in downtown Greencastle and to try out our first prototypes!
