Why do pulling something out is way harder than putting the same thing in?

248 views

Like those toddlers who get stuck in a fence or alikes. How can they put their head in but once it’s past it’s impossible to get it out again. Or even a ring, a couple of minutes after putting it in it’s harder to get it out

It is “way harder” only if the shape of the “thing” in question is irregular (think of an umbrella stuck through a mesh of sorts). Putting a needle into a cucumber is not easier than pulling it out, yet a sawtooth stinger (like a bee’s, or other bugs) will catch on while being pulled out and make it harder.
