DIY electric mixer!
Courtesy of my friend JM Custardcrusher*.
Supplies: a power drill and a fork.
Insert the fork into the power drill as if it were a drill bit. Make sure it fits snug so it doesn't come out at all when you pull it hard. Turn on the power drill and durrrrrrr.
Disclaimer: this should probably not be attempted by anyone. Instead you should get an electric mixer ;-)
*That's the alias he chose.
