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


for this project I’m going to show you
how to make proto buddy proto put is a
cool moldable dough that you can press
in the nearly any shape but after ten
minutes it magically turns to rubber
bouncy stretchy rubber all you 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 number one and while you’re
here double-check your tube is marked
100% silicone 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
of the food coloring and squirt a
generous amount into one of the bowls
remembering that the more you use the
richer your proto Kutty 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 number one releases
acetic acid vapors while curing and
smells so strongly a vinegar that it’ll
make your nostril 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 make sure you don’t
mix it too quickly or Mike’s wash 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 all got about 10
minutes of work time before this all
starts hardening up but the problem is
this stuff’s 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 10 to 15 times this
will help tame the sticky nature of the
mess and make it a lot more manageable
to work with now if any part of the
silicone starts feeling sticky again
just coat it with more cornstarch and
repeat the process until it loses all of
its 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 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 five to
ten 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 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
left a perfect impression in the putty
and created a fun little mold that looks
remarkably similar to the 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 of leftover
putty and watched it harden into an
interesting ergonomic stress ball made
just for me and perhaps this would be a
quick and easy way to make a custom pair
of rubber handle grips as well now if
you want to have even more fun with your
proto buddy try mixing a batch with neon
food coloring instead I use neon green
to make a batch and press it over an
acrylic mold I designed for a different
project then gently wrap the edges up
around the sides to let it set 20
minutes later you can see the rubber is
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 press 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 it’s curious to see
what the proto cutter would do 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 20 minutes to
completely set up into a virgin 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
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 pod 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
just to 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 project perhaps you’ll like some of
my others check them out at the king of
random Calm
