i went over to my dad's house and played around with food coloring and water. i kind of stole the idea though. so i will at least throw that at you. i did not do the same things as my friend did though, so yeah.
my grandpa found my great grandfather's old single blade razor. i had a little bit of fun with it. and for those of you wondering, it is really hard to shave with one of these. also, i used some of his old tools..
