Step 1: Materials
Old records - I got mine from a yard sale for 25 cents each.
Step 2: Melting the Records
Then turn the smaller of the bowls (middle-size if you have three) upside down on your baking sheet & place the record (centered) on top of it.
Put your record in your pre-heated oven for about 5 minutes, just until the record starts to droop over your bowl.
I don't have any pictures of this drooping because you have to be so quick with the next step, that I just didn't have time to take pictures.
Step 3: Molding Your Bowl
Mold the edges of the bowl as you desire to make wavy shapes. The more wavy & abstract the better. I have made some with less waves before, and they looks a little too plain.
You only have about 30 seconds to a minute before the record will start to cool and harden.
I really recommend just sucking it up and using your bare hands to do this unless you have skin-tight heatproof gloves.
Step 4: Suggestions for Use & Cautions
Keep the windows open, or at least have decent ventilation, while making these. The fumes can get to be a little much even though you don't really smell them. Rumor has it they may be slightly toxic, but that's generally how melting plastic is.
I took Oreo truffles in one of these bowls to a football party once. All you do is put some plastic cling wrap in the bowl before you put the food in it. That way the food isn't in direct contact with the bowl, and there's no worry about how to clean the bowl after.
I use a couple of these around my house as catch-all bowls for things like change, receipts, random cords, etc., but they also make excellent (wrapped) candy bowls.
