Squishy Slime Mix 1 cup sugar, 12 cups water, and 3 cups cornstarch in a saucepan. Stir constantly over medium heat until thickened, about 5 minutes. Place a glop in each of several bowls along with drops of food coloring in each. Place a dollop of each color into a plastic sandwich bad and zip it shut. You can squish and squeeze without getting your hands slimy!

Add a bit more of the solids, and if it’s too thick, use the liquid to thin it out.
Slime isn’t thickening! What do we do?!?!
That’s a really good question – I am not sure! I tried looking it up in my chemical reference book, but it didn’t have anything useful in it.
Hi Aurora, what would the formula look like for Psyllium and water to form the slime? Tx
SLIME is my most favoritest thing
(is favoritest even a word? i dont think so but i’ll use it anyways.)
slime is so cool slime is squishy,cool,slimey,and tons of fun

I think the recipe is for half-a-bag full of slime. I used to mix up a HUGE batch of glowing slime in our kiddie pool for glow-in-the-dark and Halloween parties… it was so much fun!
Can you give an idea of how much this makes – number of dollops is fine. Want to make it for a party with more than 10 kids. I want to have enough. Thanks
We extended this by watching the corn episode of “How Stuff Works: Food and Beverage” on Netflix. What a great lesson!
Interesting question! What do YOU think?
does the slime become more slimy and yummy if u heat it up for a longer time?
This is one of the very few experiments that didn’t get a video… do you need help with making it work, or were you just wondering?
Do you have a video for this subject? By Skylar
You can… just open up the bag! 🙂
what would be fun if you could play with it out of the bag
!
The cornstarch is the stuff that thicken when you heat it. You can substitute white flour, but you’ll need more of it because cornstarch has 8X the ‘thickening power’ of regular flour. Here’s another variation with out sugar:
One 14-ounce can of sweetened condensed milk
One T cornstarch
food dye (optional)
Combine the ingredients in a pot over the stove over low-med heat, stirring constantly until mixture thickens. Let cool and play!
*Note – you can always make edible, squishy slime out of gelatin or jell-o – don’t hesitate to experiment to see what works best!
IMPORTANT: Don’t make edible and non-edible slime at the same time to enforce safe chemistry lab procedures of never eating in the lab. Do them on different days so your kids are clear and you don’t have any accidents!
Are there any other ways to make edible slime without cornstarch; and can you make it still taste nice without using quite so much sugar?
Whoops! You’re right – I’ve edited the post. Sorry about that – yes, heat is the key to making it thicken.
In the first experiment, am I supposed to heat the saucepan?
