have you ever wanted to make your drawings come to life
no i mean actually move yeah so have i welcome to impossible science
hey everyone it's jason latimer the world champion of magic now today's topic drawings that animate
on their own now what you just saw with that dry erase board well that's obviously an illusion
but today i'm going to show you an experiment where your drawing will come to life and it uses
one of these that's right a dry erase marker so grab one of these and i'll meet you in the kitchen
wait a drawing that can actually move yeah pretty cool right now before i can get into how to do
that i want to go over this little science experiment with you see you can do this at
home take some oil take some water and if you pour them in the glass they'll separate themselves now
anybody who's ever mixed oil and water knows they will never mix up because they have different
chemical bonds but what i wanted to show you is that the oil will always sit on top of the water
because they have different densities see oil is less dense than water oh wait what's density
let me explain density is the relationship between an object's mass and its volume mass is the amount
of matter or substance that makes up an object while volume refers to the amount of space an
object takes up in other words density is how heavy something is for its size imagine a scale
with a block of water on one side and the same size block of wood on the other
given the same volume the water is heavier for its size and it will tip the scale the block
of wood is less dense than water so it would sit on top which is why wood floats on water
if we swap out that block of wood for the same size block of metal
we can see that the metal is heavier so we could see why the water would be on top
the metal block is more dense than water so it would sit on the bottom if an object floats
it's because it's less dense than the fluid it's sitting on and if an object sinks it's because
it's more dense than the fluid it was put into okay so now we know why oil was sitting on top of
water it was less dense than the water and why is that important because dry erase markers have two
major ingredients the first is alcohol that's used to dry out the ink the second is the releasing
agent that allows the ink to be rubbed off that releasing agent is made of silicone oils wait
did you say oils yes the same oils that sit on top of water check this out if you take a dry erase
marker and you draw a figure we let it dry first the alcohol evaporates and now we have only the
silicone oils we take some water and we carefully pour it into this tray see if i can get him to go
ah there he goes woohoo it's party time it's pretty cool right i can even get him to tilt wow
i could make a surfer alright i'll show you some cool things you can do with it
now you want to draw on a smooth glass surface something that's not porous and you can be super
creative you can have different colors you can have different drawings but the thinner the lines
the harder is to keep the picture together when it comes off the bottom okay now that we know
how to make drawings come off the surface you can actually transfer the surface let me explain draw
it in a small bowl and then lower it into a tub of more water do it slowly try not to break the image
now once you have that image floating around on the surface you can put it on your skin
watch
ah that's so cool well that's it for today i hope you enjoyed making a drawing move on its
own and if you did let me know click the like button and subscribe to the channel
and if you came across some cool idea of what you could do with a drawing in
the background and an object moving across the top let me know in the comments below
what you drew and until next time stay curious because the right question changes everything
