Stupid things you did when you were a kid

I watched my father inserting a tester into an electrical socket to examine its connection. The tester's head lit red every time he inserted it. I was curious as well.

I couldn't find his tester, so I had to make do with what I had. And that turned out to be a little iron rod used to clean the stove. I got upon the table, inserted the iron rod, and turned on the plug, hoping to see the top of the rod light up red like the tester.

"Reality struck through my body," is the only way to explain how I felt. 😵‍💫I was thrown off the table.
I gathered myself, half dazed, staring at the iron rod still in my grasp, wondering why it didn't glow red.

What doesn't kill you makes you stronger, right? 😜😄

So what's your story?
