During covid, I was staying with a friend and they refused to let me install one cause they were afraid their kid would flood the house. Fair point that I couldn't really argue with given how they were putting me up at a time when I needed a place.
Children will be startled, entertained, and then never do it again (in my experience).
In general, not having useful objects around the house because kids might misuse them deprives the tiny scientist of critical self-educational opportunities.
