Many interactions on mastodon are like: Me: Wow, my microwaved popcorn was too hot and I burnt my tongue! Responder A: You could maybe put the popcorn inside a bucket made of ice to quickly cool it. Me: I don't want to do that and I also don't have any buckets made of ice. Responder B: A bucket of ice can be made by putting water between an inner form and an outer form and freezing it. Me: Ok, but I don't want to do that and it would also take many hours to freeze the water. I am eating popcorn right now. Responder C: Liquid nitrogen will freeze water in as little as a few seconds and can be purchased at many welding-gas suppliers
