Filler for microwaveable beanbag warmers?

Question

If I wanted to make a microwaveable bean bag is there anything I can fill it with besides food products? (like corn, rice, cherry pits, etc) any sort of plastic or something? I don't know what's microwaveable or what holds heat. Thanks

Answer 1

dry buckwheat. It doesnt go bad. Microwave for min 30 without a glass of water, two mins with.

Answer 2

i have homemade beanbag warmer things. they are filled with rice. why dont you use rice? its inexpensive.

but you MUST place a cup of water in the microwave with it, otherwise it will explode.
