This question was made for me
Although I like to think there was some point to all my experiments. I have always taken the scientific approach. Here are a few of the more memorable ones

5 years of age or so: how far can you lean out of the top bunk of the bunk beds without falling out? Concussion, and big carpet burn up my forehead. And my mum came up to see what all the noise was

6-7 years old: Does Father Christmas exist? I devised a clever experiment involving putting what I 'wanted' in a letter up the chimney (control group) and telling my parents that I'd put something else, what present did I get? Don't know why I'm including this as it wasn't pointless, I thought I was pretty clever at the time. Although not so much when I got a smacking for revealing the results to my two younger sisters.

8ish: Can you make a hang glider out of a partially inflated air mattress and some string, and sail gracefully across the room from aforementioned top bunk? Nope, but you can smash two of your (fortunately milk) teeth out on the chest of drawers.

11 or so: stole a relay board from school to connect to a BBC Micro, you wrote lines of code and could turn (12V DC) things on and off, pretty cool. But can you use it to be able to turn your bedroom lights on and off at preset times? Once again a resounding no, blew all the house electrics and set fire to the board, my carpet and nearly the whole house.

First year of high school: how hot is a Bunsen burner? Hotter than a standard mercury thermometer can measure, but the glass end of the thermometer pinging across the room is qute satisfying. As is getting the afternoon off school when they had to evacuate the science block to safely clean up the mercury.

Quite soon after: what happens if you pour ethanol over all the chemistry lab workbenches and set it alight? A massive bollocking, 3 months 'on report' and a several hundred pound bill for new textbooks, which took a while to pay off doing a paper round.

14ish: Riding a BMX (tied to a tree with string so it could be recovered) off approx 20' rock cliff into a river to pull some mad stunts. Attempt 1: nearly castrated myself due to string being too short. Attempt 2: nearly castrated myself again due to landing on bike in quite shallow part of river

I'll add more later when I think of them

Wow loved number 11!
You were a geek in the making. But then again thats exactly the same sort of thing I would have tried doing at 11 too :)
