My father and I swung aluminum baseball bats simultaneously at each other to hear that loud "clank" noise they'd make at impact. When we connected I didn't hear that "clank".. more of a loud thud. I missed his bat and hit his hand. Broke a few knuckles and had to explain to mom why I hit dad with a baseball bat.
Death Valley has lots of these little formations on the floor in places. They look like columns about 5-6cm high. I knew they were salt, but had to lick one....yup they were salt. I was 50 years old at the time.
When I was fifteen years old, I kicked in my basement window so I could see how easy it was to break into my house. Turns out it is pretty easy.
When I was younger, after I had a bath, I decided that I would slide around the tiled bathroom floor naked pretending to be a penguin. It was actually so fun.
A friend of mine wanted to know what was in a battery so he tried to cut it open. Naturally, acid shot into his eye. The nurse at the ER told him he was the stupidest person she'd ever met.
When I was around 10 years old I really wanted to know what the inside of a wall looked like, so I dug a hole in my bedroom wall. Well, having a hole roughly the size of my hand in the wall terrified me (at the time I had, and may still have, an irrational fear of a hoard of man eating chipmunks living in the walls). I didn't want to look at it, so I put a poster over it and taped all around every edge of the poster to seal in the chipmunks.
I eventually forgot about the hole. A couple years later when we were moving I finally took down all my old posters and rediscovered the hole.
Not wanting to have my parents find out that I was ruining the walls, my idea was to find a way to fix the hole without them ever knowing.
I taped over the hole with packaging tape, then did kind of a paper mache over it with paper towel and Elmer's glue to kind of match the texture of the wall. Then, being pretty artsy, I mixed acrylic paint to match the color. As far as I know, they never found out about my journey to the center of the wall.
I was studying in my school library's study room when I was younger (it was a small library). Saw the emergency door with a sign saying "DO NOT OPEN, ALARM WILL SOUND" and I thought "What will happen if I open it? Will the alarm really sound?"
Turns out the alarm is really loud.
As a teenager in the mid 80s, there were two ways for me to find out why a golf ball is so bouncy: go to a library and look it up or cut it open with a pocketknife. It cost me six stitches to discover it was a tiny hard rubber core with a lot of little rubber bands wrapped all around it.
One time I found this pile of crap in the school yard. It looked like a totally legit fake pile of crap.
I tried convincing my friends that it was fake poo.
They said prove it.
I poked it. And as I poked it I realized I made a grave mistake...it was in fact, a real pile of crap.
My finger sunk right into it, everybody laughed. I ran to the bathroom to clean my finger.
Just assume all crap you see in the grass is real.
One time I took one of those little paper cups (the kind you might have in a bathroom for taking a quick drink of water for swallowing a pill), filled it halfway with water, and then took it to my room and set it on my dresser. I then proceeded to light it on fire.
My dad smelled the smoke and burst in wanting to know what I was doing. I told him I wanted to see what would happen when the fire reached the water.
He was angry at me for playing with fire and doing so in the house. I think he was also disappointed that regardless of what happened, I clearly had no plan for what to do after I lit the fire.
To put your curiosity to rest, I will inform you all that once the flames reached the water level, the fire went out. SCIENCE!
See how long I could go without sleeping. I ended up falling down the stairs around the third day. Too tired to get up I just slept where I landed.
I put muscle relaxant under my eyes once to see if it made me cry. Sure did.
When I was about 14 I was getting into programming and learning about 'progz' / hacking. I downloaded a virus just out of sheer curiosity. Wasn't gonna send it to anyone, but for some reason I thought it was cool to have. Well the avatar thing for it was a folder, so naturally I see what's inside and boom! Brand new family computer straight down the crapper!
Not me but my sister once decided to test whether stepping on a rake would make it spring up and hit her in the face like in cartoons. Spoiler alert: it did.
When I was about 12 I wanted to know what would happen if I stuck a basketball pump opening to the opening of my penis and pump air into it. I legit thought it would make it bigger. I was sadly mistaken. Pissed air for a good hour and endured the worst pain in my life.
I once poured water onto a light bulb (that had been shining for hours). I wasn't really thinking and kind of expected it to make this 'psshhhhh' sound. Well it exploded right in my face. Thankfully I didn't get hurt, but I could have been blinded..
Licked the red part of the cigarette lighter in the car.
I licked a Himalayan salt lamp. Tasted like....salt.
When I was 5 my genius brain decided that if I just held the toilet paper in place while I peed then it would save time so I wouldn't have to wipe after. Soon as I felt it soak through I got freaked out and and flung my hand out and up, effectively splootching the wad on the ceiling, where it stuck. Grandma wasn't happy.
When I was a kid, my family and I were very religious. My parents were quite strict. I broke an expensive crystal vase when no one was home. I knew I'd be in big trouble. I prayed my parents wouldn't notice and tore two $5 bills that I had into shreds as a sacrifice to God to help me. They never mentioned it to me, but it seemed cringeworthy when I got older.
When I was little, I noticed some brown liquid leaking out of the battery compartment on one of my toys. For some reason I decided it might be BBQ sauce, so I tasted it.
It was battery acid. Burnt the tip of my tongue, not pleasant.
My sister and I found a duck egg and wanted to see if we could hatch it. We thought the microwave was a perfect way to speed up the incubation process. It sped up the explosion of an egg in our microwave. The smell lingered for weeks.
When I was around 10 I wanted to see what the inside of an electric cord looked like so I cut one in half with a pair of scissors. I didn't want to be electrocuted so I turned the lamp off first.
