I'm not a hundred percent sure but it depends on how long. If it's only 1sec-1min it would make it warm, maybe even to 3-5 minutes as well. Around 5-6 minutes the stickers would start to peel, and fall off around 7-15 minutes. It might start to melt around 30 minutes, and this is only if it has no metal in it. If it has metal then it might explode and catch the house/building on fire/ Highly don't suggest that.
I would expect the mechanism inside to get damaged - it might rust.
