Wind Up Fire Alarm
MrPete222 (Your YouTube Shop Teacher) has a What Is It Series. Since I only know about half the tools he shows I usually just watch the answers episodes. In the latest one he shoes off a wind up fire alarm along with some information about it.
I recall some of the "discussions" here on the topic. I thought some of you might be interested strictly out of morbid curiosity.
Maybe you guys can iterate your opinions of them in the comments on his video. LOL.
