Try that (not in your oven [}:)]) the missus may not be happy.
Stick some blue tack in the centre of the revolving plate, place a match standing up in the blue tack, set the match alight, close the door and start cooking you will have your own little fire storm in the oven very impressive! Like plasma balls.
WTF can someone explain????
If doing experiments in your microwave remember to put a glass of water in there as well -- this absorbs the microwaves and stops them building up to dangerous levels.
I think someone has dedicated there whole life to doing weid microwave experiments and has a utube channel. (pretty sad) lol
Marshmallows are good too ...
Ruined a microwave when niece kept puffing them up to orange size [}:)]
