How To Make “Proto-Putty” (Modified Oogoo)


For this project, I’m going to show you how
to make Proto-Putty. “Proto-Putty”s a cool moldable dough you can press into nearly
any shape, but after 10 minutes, it magically turns, to rubber. Bouncy, stretchy rubber. All your need for this project is a box of
food coloring, a tub of cornstarch, and a tube of 100% silicone. It’s extremely important you get silicone
#1, and you’ll be able to confirm that’s what it is, by looking at the top of the tube. While you’re here, double-check your tube
is marked 100% silicone as well, just to be sure. Now to minimize the mess we’re about to
make, it’s going to be helpful to have two disposable paper bowls on hand. Grab some food coloring and squirt a generous
amount into one of the bowls, remembering that the more you use, the richer your “Proto-Putty”
color will become. The silicone caulking goes in next, so carefully
squeeze a big blob of it directly into the food coloring, until you feel like you’ve
got enough. Keep in mind that Silicone #1 releases “acetic
acid” vapors while curing, and smells so strongly of vinegar that it’ll make your
nostrils sting. So you might want to think about mixing this up outside, or at least
in a well ventilated area. Use something like a popsicle stick to slowly
fold the silicone and food coloring together, and make sure you don’t mix it too quickly
or it might splash out and stain your clothes. You’ll be able to tell when the two components
are combined, because they blend nicely into a solid, and uniform color. Now it’s important to note that as soon
as the food coloring is mixed the clock is ticking, and we’ve only got about 10 minutes
of work time before this all starts hardening up. But the problem is, this stuff is ridiculously
sticky and extremely difficult to work with. But if you drop the blob into a big bowl of
cornstarch, then generously coat the outside with powder, the silicone becomes a lot easier
to deal with, because the powder prevents it from sticking to anything. Now if you don’t want to turn your hands
different colors or end up with super sticky fingers, now is the time to put on a pair
of disposable gloves. Of course gloves are optional for anyone feeling
adventurous, but you may regret not using them. Just saying. Flatten the silicone blob down into the cornstarch,
then flip it over a few times, kneading it into different shapes, and repeating the process
about ten to fifteen times. This will help tame the sticky nature of the
mess and make it a lot more manageable to work with. If any part of the silicone starts feeling
sticky again, just coat it with more cornstarch, and repeat the process until it losses all
of it’s tackiness. After around two minutes of kneading the cornstarch
in, the color of your silicone putty should brighten back up and start feeling a lot like
like Play-doh. When it’s thoroughly mixed to the point
where it doesn’t stick to your hands anymore, the “Proto-Putty” is finished, and ready
for immediate use. You can mold it, squish it, or press it into
whatever shape you want. Just remember, you’ve only got 5 – 10 minutes
of work time before it turns to rubber. So whatever you’re doing, make sure you do
it quickly. I tried making impressions of some stackable
plastic bricks, and you can see that after only 15 minutes the rubber is already so stiff
we can pull it out of the mold. Popping the bricks out, you can see they’ve
left a perfect impression in the putty, and created a fun little mold that looks remarkably
similar to kind I made in a previous video. The final product is extremely stretchy, very
rubbery and amazingly durable as well. Now this idea works because general purpose
silicone, is activated by moisture. So by blending in a generous amount of food
coloring, the silicone gets triggered, and instantly begins the curing process. Just for fun I squished up a ball a left-over
putty, and watched it harden into an interesting ergonomic stress ball made just for me. Perhaps this would be a quick and easy way
to make a custom pair of rubber handle grips. Now if you want to have even more fun with
your “Proto-Putty”, try mixing a batch with “Neon” food coloring instead. I used “Neon Green” to make a batch, and
pressed it over an acrylic mold I designed for a different project, then gently wrapped
the edges up around the sides to let it set. 20 minutes later you can see the rubber has
cured, and we’ve got ourselves a cool little mold for making custom bars of soap. I formed another chunk into a hook shape,
and pressed it onto my wall, to make an improvised key hook for hanging car keys. I made a clip for my workbench to prevent
power cables from pulling out of place. And I even tried wrapping some around a fork,
to make an ergonomic handle grip, that fits the shape of my hand perfectly. Now I was curious to see what the “Proto-Putty”
would do if we didn’t use any cornstarch at all, so I whipped up another big batch
and slopped it straight into the mold. Surprisingly, it still only took about twenty
minutes to completely set up, into a version even stretchier, and perhaps even more durable
and resilient than it was before. The problem is that without cornstarch, it’s
difficult to work with, and really hard to remove air bubbles trapped at the bottom. Now check this out. If you want to fuse two
of your rubber creations together, all you need is a dab of fresh “Proto-Putty” to
bind them. Press the pieces together, let the putty cure,
and just like that, the two, have become one. “Proto-Putty” is a fun rubber that’s
surprisingly bouncy, which means you can make rubber toys, roll your own bouncy balls, or
make just about anything else you can think of. I tried rolling a piece of yellow putty into
a loop, and turned it into a custom silicone wristband. Then pressed another piece into a taco shape,
which made a custom rubber base for watching movies on my smartphone. This quick and dirty pinch pot is great for
storing paper clips at the office, and I even tried making a screw-on lid for Mason jars.
Which is easy to use, and surprisingly watertight as well. “Proto-Putty” is fairly stretchy in general,
but the thicker you make it, the more durable it’s going to be. It works great for impression casting, like
making half-molds of little glass bottles, but if you’re tempted to use it for making
custom candy molds, you might want to reconsider. Construction Silicone can be harmful if swallowed,
and can cause serious side effects if it gets inside your body. So rather than using it to make candy molds,
it’s probably better to just make toys, crayons, or little rubber erasers instead. Well now you know how to use a few simple,
and very common materials, to make huge batches of “Proto-Putty” on a budget. So you can channel your power of creation,
and make anything you want. By the way, there’s a different kind of
“Food Grade” silicone you can use for making candies, and I’ll put a link in the
description to where you can find it. Well that’s it for now. If you liked this

  1. Man, this silicone is sticky! I tried and failed trying to mix this with just my hands. I was cleaning silicone off of my hands for an hour. I'll keep trying until i get it right.

  2. The food coloring makes the silicone triggered because food coloring killed silicone ten times in Roblox Phantom Forces.
