When I learned from Jon Lee in S Club 7 that tanning beds are meant to be unhealthy because they can burn your skin and give you cancer, or even kill you if you get stuck inside and burnt to death, I thought they were just another term for deckchairs, before I knew what they actually were. Would make more sense to call them machines instead of beds. I kept thinking 'why is it bad to lie on a deckchair with a towel, everyone does that in Summer!'
This is actually an early adolescence belief: when I was about twelve through fourteen, I thought viral videos were ones that gave your computer viruses.
One time, I was playing in the living room while my mother was watching something and a character on the TV said, "Oh! I forgot to close the fridge door!", and so Mum turned to me and said something along the lines of, "Don't you ever forget to close the fridge door."
Then later, I saw an episode of "Spongebob Squarepants" (which is this wacky cartoon about a talking sea sponge) where Spongebob gets sick from leaving his fridge open.
Both of those made me think that every time you left the fridge door open, something random, but always very bad, would happen.
I used to think that in order to top up your mobile phone you had to open the back of the phone and put actual money in it. And I thought that when you phoned people the phone would actually eat your money.
I used to believe that hitting the Break key on the keyboard would cause the computer to be ruined.
When I was little I thought there really were aliens on mars.
Up until was 11 I used to think that in order to get an email address you had to phone up an email address office and they would give you a random address and password
I used to believe that in order to top up a mobile phone you had to open the back and put actual bank notes or coins in it, and I thought that as you were calling or texting someone there was a little mouth in the phone that sucked up all the money.
When I was little I used to play one of those art games on the computer where you can print out your picture. I didn't know how a printer worked, but I knew there was a wire connecting the printer to the computer. I thought that when you printed something out, the paper with picture you were painting would roll up and travel through the wire to the printer, then when it got to the printer, it would slowly unroll it (when it would actually be depositing ink on the paper) so that it wouldn't tear. I finally realized my mistake when I was about 4 and we ran out of paper, so I asked my mom how to put more in the computer.
For a few months, I used to believe that everytime you hit the space bar, more space is generated in the sky and outer space. Maybe it is true, because nobody knows how big outer space and the sky is.
When my mother was little, she believed that every time you put a record on the musicians would have to play the music. As a result, she never played records in the evenings or at weekends so the musicians could have some time off.
I remember hearing paedophile on the news a lot and I became familiar with computers while i was young. I honestly believed the PDF was short for pedophile since file is pbviously connected to documents.
e.g. I'll attach a pedophile to the email.
I used to believe that Windows was written in QBASIC. (This was at the time of Windows 3.1.)
I used to believe that an elevator was a magical room that teleported you somewhere else in the building. Then i learned that this "magical room" was just a box hoisted up by a machine.
I used to believe that FAX send real papers.
I thought that FAX documents went through the electric line. No one told me the structure of FAX.
My parents got our first computer when I was about 9 and windows 95 was just released. I had no idea what I was doing and was just going through all the random "folders" looking for games. My cousin's computer had Oregon Trail, and this computer was way better so my "Oregon Trail" game must be amazing!
I must have done something wrong and the computer froze up saying "This program has been shut down due to an illegal operation." I FREAKED OUT and unplugged EVERYTHING from the computer... The power, the screen, the keyboard, mouse, and the printer before hiding under my bed for hours. I was convinced 'they' were coming to arrest me for breaking some law. I remember literally crying that I was going to be taken away in handcuffs.
I used to think that calculators worked because someone had preprogrammed all the answers into them ahead of time, and I pictured people in factories programming all the answers in, one calculator at a time. When they came out with calculators that could display more digits, that only made things more amazing because of how many more answers they had to program!
When I was a kid, I used to believe a nuclear plant was a clouds plant and could make magic clouds.
I believed that an Xray was this piece of fabric that you would go behind and would rip out your bones. After displaying them on a screen, they would sew the bones back into your body. When I had to go to the doctor so I could get an xray... you could tell that I freaked out.
When I was a child, I used to think that the liquid inside a can of spray, hairspray, insect spray, lubricant spray, looked like the spray that came out of the can, and that it sloshed around inside, all squishy, but still in the small particles of the stuff, or in other words, dense mist.
