We recently received a donation of old vinyl records and I wasn't sure where to go with all of them.  So we made a craft---
Vinyl record bowls-
Preheat oven to 250 degrees
Place your record on an upside down metal bowl and stick in oven.
Once you see the edges turn floppy, with oven mits take record out and place in another slightly larger bowl and allow  to cool for 15 mins or so.
The bowl will be come hard.

After the bowls were made we decorated them with paint and stickers.  They turned out really neat and we had lots of compliments!
