hi I'm Sophie and welcome to my world and it's time for another Wayback
Wednesday and I'm gonna take you way back way back before slime was the
craze that it is today I'm gonna take you to when I was doing science projects
and I was in love with oobleck the original slime so I hope
you like this way back Wednesday make sure you watch it all the way to the
end because there happens to be a blooper so Wayback Wednesday coming at
you Oobleck
hi I'm Sophie and welcome to my world well if you watch my channel you know I
love science and you know I love making a mess and so today I'm gonna teach you
how to make something really fun it's called Oobleck and all you need is some
cornstarch and some water and a place to get messy
okay so the thing about Oobleck is it's super fun but it's super messy so if you
can't be outside then what you really want to do is make sure that your work
surface is totally covered I'm going to use a brown paper bag but I would
suggest using a tarp or garbage bags or something that you can really really
cover your work surface because this stuff does get really super messy super
super fun but it's super super messy you're going to need a bowl and you're
gonna need a spoon and then you're gonna want to have a cup of water on hand now
I've also got a little measuring cup here this is 2 ounces there's gonna be
four of these per cup of water I'm gonna be using this to help make sure that I
get the right consistency for my Oobleck and in this case I'm going to be using
half a cup of cornstarch cornstarch is awesome you find it in the cooking aisle
they use it for thickening things like gravy so it's either gonna be in the
cooking aisle or it's gonna be in the baking aisle so this is cornstarch you
are gonna want to have cornstarch so the first thing I'm gonna do is prepare my area here
I've just taken a brown paper bag and cut the bottom off so it lays nice and
flat and I'm gonna take the cornstarch the 1/2 cup of cornstarch and I'm just
gonna pour it in see what I mean about it being messy it's messy already and
hasn't even gotten wet yet and pour it all in to my bowl now here's where you
have to be patient and you also have to take your time with the amount of water
that you add because here's the thing if you add too much it's gonna get too
runny now it'll be really fun to still play with but it won't be
as cool if as if if you take your time and get it to the exact right
consistency so I'm gonna start with just two ounces of water let me fill this up
and I'm just gonna pour it in and then I'm just gonna kind of swirl it around
the problem with Oobleck I mean it's a problem but it's also a cool thing about
oobleck is that there is no one set real recipe for it because it varies
from place to place and you know it varies with how hot where you
live is or how much air pressure how high above sea level you are there's all
kinds of things that that work and play here okay so now you can see I was able
to get that water in there but I'm still got a lot of dry off to the side here so
what I'm gonna do is I'm gonna take another two ounces but I'm not going to
pour the whole thing in I'm going to start by just pouring half in so that's
gonna be like half there that's gonna be about three ounces of water in here so
far okay now I'm at whoa now it's starting
to get good okay so kind of swirl it around in your bowl you can see how it's
kind of like getting thick and liquidy at the same time that's what's so cool
about oobleck now here's the thing if you want to I mean get super messy you
can add food coloring to your water the only thing about it that I've found is
that it really stains your hands when you're playing with it and so you know
the parental units may not be so excited about having stains caused by food
coloring everywhere so that's why I would suggest just using plain white
because it's just as much fun okay now that was three ounces of water and that
is about the consistency that you want so that was half a cup of cornstarch and
three ounces of water and check this out this is what makes it so cool so now you
get your hands in there once you've once you've got to a point where it's like
you can tell it's like pretty cool pretty together and you can start
playing with it with your hands and it's it's if this is the coolest stuff
because it's like it melts like it starts like watch this like it'll be
like a ball but then it melts I mean and I can't even begin to describe the
feeling it's smooth but it's chunky and it's sticky and gooey and it's just
plain awesome and now it's time to play and answer that age-old question is it a
solid or a liquid only the Oobleck can tell for more messy misty icky ideas
come and check us out at sophie-world.com don't eat it
and now it's time to play and answer that question is it a solid or is it a
