video Making Imitation Silly Putty
It seems everyone tries but get this wrong? I have found the perfect proportions. So no more glue balls. This isn't slime. This video is my recipe for making a silly putty like substance. I am a chemist and it works perfectly. It is a polyvinyl acetate polymer.

Metric measurements
25mL glue
20mL water
15mL Saturated Borax Solution

No matter how many times I do this, I never get bored making it. It acts like snot but it isn't sticky. It flows like slime but isn't greasy. The best part is you can make this "Silly Puddy Like" substance at home. All you need is the Borax (Sodium Borate) and Glue.

I thought the puddy worked very well, right now I've promised my 4 and 5 year old neighbors that ill make some for them. They thought it was Flarp.

Oh my gosh! I think that is the weirdest thing about home made silly putty. It flows like slime but isn't greasy! I also feel like I need to wash my hands after I play with it.

can you add paint instead of water?
I don't think that would work, they are different substances. If you want color, try adding food coloring!

Where are the instructions?

You just mix the three ingredients together to make the putty.

Throw it on the roof in a cinema and watch people below it freak out when it falls :D

What is borax solution?

Its like soap flakes. I think.

does it bounce?,  can you use it to copy the funnies out of  the news paper?

To make silly putty you can use liquid starch. The best ratio is 2 parts glue per 1 part liquid starch and stir until it becomes thick and then knead it like dough to even it out. The more water you use in this version creates a less viscous slime. I tried it once with no water and it made something closer to rubber. Not as much fun as slime.

Id just like to say this isnt quite a silly putty substance. This is what most preschools, and fun chemistry books call flubber. Ill try adding more borax to see if it turns out more like silly putty.
silly putty is also played by elementaries and highschools.................

I am trying to do a project for my chemistry class on this experiment. Does anyone know how the chemistry actually works behind it?
Yeah, hum actually I'm trying to figure out this whole site for posting because I found one of these where the person went all out to explain and provide links for everything and I wanted to say- way to freaking go- thanks man so let me back out of here and figure out where I was and I'll update you. It is not exact but if you haven't turned in your "I'm going to do this" sheet yet, you can switch or you may find one of the resources to be "silly putty"

is there maybe an alternative for borax?

great we tried it in science class

Very cool, it's not exactly like sill putty though, is there a way to make it more solid?
More borax

Would more Borax make the substance thicker and more Silly Putty like (i.e. less viscous)?
Viscous: Having relatively high resistance to flow.

Viscous: Viscosity is a measure of the resistance of a fluid which is being deformed by either shear stress or extensional stress.

So when you say less viscous, you mean thinner, or less thicker\solider. So in your case, you would say: "(i.e. more viscous)?"
Great job! Cool video too, where did you get Borax?
i can never find borax
You should be able to find it in the grocery store laundry aisle. 20 Mule Borax is a common brand. It may also be listed as "Laundry Booster".
My local Wal-Mart carries Borax. I add it and Baking Soda to the laundry to save ca$h and make the clothes even cleaner.
I tried making this stuff. I didn't have any white glue, so the first time I tried using Mod Podge and it didn't work, so the second time I used wood glue and it worked great. I play with it constantly. Btw this stuff bounces a bit.
That is cool. Do you have to keep it in a plastic bag so it doesn't dry out?
love the music you use xD

I like this kind better than the original because I like making thing better than I like buying things.

very cool. I have found that it is best to use a washable children's paint such as Crayola or tempra (SP?) so that if the kids (regardless of our age) get it on the carpet or clothes, it will wash out much better. I usually water down the paint (about 50/50)

I remember we made these in kindergarten. :] Mine got stuck in my hair. HA HA!
we made this stuff for earth science and she told us if it gets on our close use vinegar to get it off
are you sure you didnt blow your nose a lot to make that?
does it bounce like silly putty or copy newspaper print like silly putty?
