Projects
Need some air? Pierce the sky with a bike-pump-powered air rocket you can shoot within city limits.
Or make rings around people with three different
versions of the vortex cannon, launching toroids out
of thin air. Power hungry? Juice up small electronic
devices with waste heat from a candle, using
a steampunk Seebeck generator built from scrap.
