I used to believe that ice cubes were only cold because they were left in the freezer all the time. If you left them out they would simply become "warm ice." I was so insistent about this that one day my grandmother got fed up and told me we were going to do an experiment. (This is when I learned what "experiment" means.) She left some ice cubes on a plate by my bed and told me to check them in the morning. Of course when I woke up the plate was full of water, but I wasn't fooled: I was sure my grandmother had come in when I was asleep, taken the "warm ice" away, and filled the plate with water. It never occurred to me to wonder why my grandmother would be so concerned with hiding the truth about ice from me.
I used to think that GLASS and GRASS was the same thing. I always wondered why windows weren't green...
when I was a little boy I thought that there is metal and iron. I didn't know that iron is metal too. Till I found out that iron IS metal and copper is metal and aluminium....
ah, and I also thought that steel plate is another kind of metal too.
the second thing I believed is that real iron, real pure iron is so heavy - you can't lift it
When I was little I thought everything could be made out of water or turned back into water! Gold, silver, anything could be heated up and turned into water, even people. I have no idea why I decided this was so, but it wasn't until a field trip in 5th grade to the water refinery that I was informed that not everything was made of water.
Until fifth grade, I used to believe that ice was always a constant 32 degrees F. When I found out that a piece of ice could be COLDER than that, it really blew my mind.
I used to believe, in fact I think I still do, that you can cut a pane of glass into any shape you want with a pair of kitchen scissors if you hold the glass underwater. I seem to remember trying this and it working but that may have been a dream
When I was in 2nd grade I was told by my best friend, if I placed a rock i a ziploc bag with some mud and buried it, it would turn to gold.
I used to believe that medicine could only make you better and wasnt harmful, which eventually lead to me drinking an entire bottle of medicine....
I remember doing it, my logic was 'Mum makes me drink this when Im not well and it makes me better....so even though Im not ill, itl just make me feel even better!'
My mother didnt agree
When I learned that oil came from dinosaurs I thought that the dinosaurs were still alive underground and oil drills were drilling down to them, into their bodies and sucking the oil out of the poor beasties.
I saw a headline in the news paper that read, "Mixing alcohol and gasoline is explosive." So my friend and I got some gas and rubbing alcohol and tried to get it to explode by mixing it together. Luckly we didn't try lighting a match.
i used to believe that if you held hydrogen in one hand and oxygen in another and clapped that water would come out.
i just found out today and i'm 15.
I can't remember what Superman film it was, but there is a scene where Superman gets a lump of coal, squeezes it really hard and turns it into a diamond for Lois.
I thought, why don't people get one of those car crushing machines and then fill it with coal, you'd be loaded!
i used to think that fire crackers were made from crackers that you eat....i was very confused and curious for a long time.
When I was a child, I was thinking about matterials in general. As had no idea where to start, I started with the fact that some things were solid, some were liquid and some were gasses.
I not yet had made the connection between ice, water and steam, so I thought that everything that is liquid must have some water in it. I just could not figure out how much. If something would be solid, the water was gone.
when i learned about atoms at a young age, I never really comprehended how small they were. Whenever the sun would gleam off dust particles in the air, I thought what I was seeing were actually atoms, and I thought I must have some special sight super powers since a book I read said atoms were invisible to the naked eye. (I also thought "invisible to the naked eye" meant it was literally invisible unless your eye was 'wearing' special lenses)
My friends and I actually believed that once you buried fake gold, you could dig it up a day later and it was real. We tried to sell a bunch we dug up to pasisng cars in front of our friend's house.
When I was a kid there was regular and unleaded gasoline. The only difference, in my mind was that the regular (by default the "leaded" gas) was heavier.
I thought that hydrogen was pure water (since I knew hydro- meant water) and H2O was impure some how
I used to think that all chemicals were orange liquids, and that a chemistry lab would have a load of test tubes in it all filled with the same coloured substances. I don't know what I thought solids, gases and non-orange liquids were supposed to be!
My cousin once told me that glass was made from ground up beetles, and I believed her!
