ColinFurze is a bit of a mad scientist/mechanic. He has built some rather interesting devices in his workshop. You may recall his wrist mounted flamethrowers. Click here to check that out.
Well now he has been asked to make a thermite launcher.
First up he needed to make thermite and come up with a shell design to could be launched.
Next up he built the launching device. He uses compressed air and a push rod to push the thermite shell out of the barrel.
And here is the final video showing off how he can throw thermite.
