I also put our phone in a bucket of water. My dad asked me to hold it but I was already carrying a bucket of water so I just put it in the bucket.

I broke the screen on my laptop, but that was only after having it for like five or six years. And even after that, I still used it as a closet web server for years after that with SSH.

Edit: I think I was about 16 when that happened.

I suspect i might be the winner here. My friend had an alley behind his house along with a nice strip of open land near a busy road. Eventually a strip mall was built and then another large commercial building started to go up. Being basically behind my friends house we walked over to this new building on weekend to check out the construction site.

The building was being built with cement block and had lots of scaffolding and yet-unused block scattered around. I found a pipe-bender - a very heavy tool made out of high quality steel - and found you could just tap on of these cement blocks and it would shatter to pieces. I was fascinated, as were my friends. I have no idea how many cement blocks we destroyed over the next couple of days, but it was a huge number. Then we decided to see if we could go through a wall with the pipe bender… we could indeed, making a hole in the side of the building we could walk through. Looking around we eventually realized what we’d done was awful… we had decimated this construction site. We finally slinked away and come Monday when the crew returned, police were called and neighbors interrogated but thankfully with privacy fences all around, none of the neighbors saw anything. 11 and 12 yr olds are stupid.

Sigh…

When I was in the 3rd grade, our class had to do reports on countries around the world and we were all assigned a country. I got Egypt. Coincidentally, some friends of my parents had recently gotten back from a trip to Egypt. My parents asked their friends if there was anything I could bring in to use for my presentation. They let me borrow this little statue they got. It was an eagle with a hat, I think it was a depiction of Horus. It was carved out of some really nice white stone, maybe marble or something? I brought it into school, put it on my desk, and waited patiently to stand up and do my report. When I stood up, I bumped my desk, and the statue fell to the ground and broke in half.

Now monetarily this may not have been the most “expensive” thing, but it was the souvineer that this family brought back from Egypt that they had on their mantle to always remember the trip. It was priceless.

Why the fuck would you let a 7 year old bring your breakable souvineer to school for a class project?

Anyway, those people stopped being friends with my parents after that, so I have a feeling it was either expensive or meant a lot.

This hurts me to think about. Why did you have to ask this question?

When I was around 12, I was learning about overclocking, and accidentally killed my dad’s graphic card, an Nvidia FX 5900.

I vividly remember launching The Sims 2 to test my overclock, when suddenly the screen started turning on and off (the video driver was probably crashing and restarting), and after I reset the PC, there were 2 green lines on the screen and XP was stuck in 640x480 16 colors because not even the basic display driver was able to load.

My dad was mad obviously because it was an expensive card, the damage wasn’t covered by the warranty, and he was into gaming too at the time. I was stuck with integrated graphics for about a month while we waited for the geforce 6000 series to come out.

I was so scared of overclocking after this happened, I didn’t try it again until a few years later years later when I had my own computer (and killed another card, a 9800GX2).

I grew up in a very unorganized town that wasn’t really regulated with traffic laws. I learned to drive a truck at about 12.

When I was 14 I was driving my dad’s truck around town. I suddenly had the urge to see how well the brakes worked. I drove fast down a gravel road than slammed on the brakes as hard as I could. Within seconds it blew both front brake lines.

Later that same year in the winter I got the truck stuck on some ice. It wasn’t bad, I just happened to stop on a very slippery patch of ice and couldn’t move forward. I got the idea that as the tires spun, they were getting hot which meant it was melting the ice. If I did it long enough I would eventually get down to the gravel. I got impatient and spun the wheels faster smoking them like crazy while the engine roared. In the middle of the noise and smoke, a tire exploded and the truck jumped and deflated. I had blown out a tire.

Dad wasn’t happy with me for a long while because the truck went to the shop and we had to pay a lot of money to get them fixed.

At the very least, I never made these mistakes again.

I’m not sure how much my brother costs, but the three of us brothers were running across the top of monkey bars and jump kicking each other. I kicked my youngest brother off and he busted his head on the ground. It’s ~40 years later and he still has the scar on the back of his head.

I once broke my neighbor’s sliding glass doors with rocks.

A neighbor kid and I were really stupid when we were 9-10 years old, and my next door neighbor’s house had been empty for a while because they rented it out. So we thought it would be a good of fun idea to go through the broken fence between our yards, and chuck the decorative rocks (pretty big ones, not pebbles) at the glass and make it shatter. We broke one open, and then another, then went inside to check out the empty place. We started to go at the third one when my brother came outside and heard the loud smashing.

Cops were called, in the end both of us were very apologetic and told them everything.

My kid stuck a big ol donut magnet on our TV and ruined the screen.

As a kid, I kinda had anger issues and would get frustrated easily. I broke the screen of my GBA SP by throwing it against a wall after not being able to solve a room in Mario vs. Donkey Kong. Similarly, I threw my iPod Touch on the floor after losing in a game called Bad Apples which broke the glass but the iPod itself still worked afterwards.

I really wish I still had that SP, as replacing the screen isn’t that hard. It even was a limited edition one as well…

Was going through some semi-justified teenage angst stuff back in the day and my laptop was having some small issue, so I smashed my laptop.

I’m not normally prone to anger - then or now, so that was particularly out of character for me. I also wasn’t able to replace it for a long while, since I wasn’t like, rich or anything like that.

Honestly though, I’ve never regretted it. Given the circumstances (tl;dr: poor upbringing, loneliness), I can totally see why someone would lash out like that eventually.

Crashed the family car on my first day driving. Into our house. Our driveway is a mini hill with a turn to get in and then loop to the side with the corner of the house being at the corner. Accelerating up the little hill meant the house jumped in front of the car! As it was my first time driving, the blame was placed. Firmly on dad, as teacher.

Luckily the damage wasn’t too bad to repair, but still the two most expensive things were broken on one day.

Xmas ornament my parents got of QVC or something. I fell into(onto?) the mantelpiece because I’m clumsy and I was much younger at the time and I knocked it off. It was actually my favourite ornament too.

When I was 6 I microwaved a metal measuring cup full of water, which ended up arcing and burning out the transformer. Apparently it fucked up my parents’ finances for a while at the time
