How NOT to Pour Aluminum Metal

Feckin egits, do they not know that the aluminium was not unstable but the water/moisture in the tools were. When you pour hot aluminum in the mold the water explodes, it turns into steam instantly and the volume of steam is 1700 times the volume of water (1/1700) so when the water/moisture pops it will push the aluminum away in a split second just like on the video. To prevent this you heat all the tools your using, not to get them hot but to dry all the water that might be there.
