Step 5: Coloring Oogoo
I was pleasantly surprised to discover that all it takes to create vibrant colors in Oogoo is very small amounts of linseed based oil paints. Apparently the pigments in oil paints are very fine and dense so a little goes a long way.
About the equivalent of 5 or 6 drops of oil paint per teaspoon of silicone will result in solid colors. I mix the color well with the silicone before adding the corn starch.
While you can leave it white, it is a good idea to add some color to make it easy to see if you have a well mixed batch. Adding color does not appear to significantly effect the hardness or flexibility of the final result.

I would not stick this in my ear though as others suggest to make ear buds.

You're great that's a super post and idea. Do you have used it to make earbuds actually? Excuse-me if I missed something...I did not see any earbuds yet.
Keep on the good work :)
The good thing is that this stuff doesn't adhere to skin or hair once it's cured (unlike the epoxy-putty earbuds), so it's not very painful to get it out of your ear and doesn't require you to put Vaseline in your ears. The bad thing is that the silicone emits pure acetic acid as it cures, and it makes your ears feel uncomfortably hot and stings a bit (I tried it with Vaseline, and it still felt like my ears were by a hair dryer). Doesn't really hurt, but it's something to be aware of.
They sound great. The bass response and overall clarity are better, outside noise insulation is awesome so I can have the volume MUCH lower, and they're a LOT more comfortable to wear than any other earbuds I've had, including themselves when they had just the standard eartips on. I play in a small band, and I never use earbuds because they start to fall out about halfway through the second song, but these definitely will make me change that because they're comfortable and they STAY where they're supposed to. I'd highly recommend doing it.
Yes, acrylic paint can be used to set up the silicone caulk faster. It can be used to color solvent thinned silicone to make paint or to color Oogoo. It can also be used to get thick amounts of caulk to set up to make molds.
Adding a few drops of water or glycerin per tablespoon of silicone will also work to set up thick amounts of caulk and make it usable for molds.
However, using acrylic paint, glycerin, or water, while useful for making molds, tends to remain sticky and hard to work and then it sets up. It does not give you the working characteristics of Oogoo.
The Oogoo mix has similar characteristics to Sugru which means you can hand mold it into all sorts of forms for the few minutes that it is in a putty or claylike condition. It can be hand smoothed. Adding more or less starch also allows you to have fairly precise control over how long the Oogoo takes before it sets up.
You could try and form it directly on the pumpkin and after it sets up for a couple of hours see it it stays stuck. If it peels off, you could try super gluing it back on.
