Gallium Slingshot-Dart Mould

Description

For getting up to mischief!I had some 'neighbours' running an illegal bike stealing business, and wanted a better look in their shed :)However, I never tested these to success (though I only did two tests, indoors).The dart is designed to spin from flight, and to cut with the tip, to remove the aluminium-oxide where it makes contact, though Gallium's viscosity was a problem at this scale.Also it's very wasteful to make the whole dart out of gallium! Really needs to be just the tip.
