Introduction: Oogoo Mixer on the Cheap (avoid Messy Hands :))
Oogoo is a very useful tool to have in every DIY'ers inventory. It is a versatile substance, providing great adhesive,
and structural (flexibility) properties, it can be used as a supportive material for fixing items, or as a stand alone material
for constructing molds and various parts. Oogoo is a substitute for Sugru - a product which is a lot prettier and produces less mess, yet has a very heavy price tag. You can check out the following article for the uses of Sugru by Mr. Whitson Gordon from lifehacker - http://lifehacker.com/top-10-diy-miracles-you-can-accomplish-with-sugru-756259927. You can also check out the Sugru web page in case you decide to buy the real thing - http://sugru.com/. And to get the full scoop on the Oogoo check out the article by Mikey77 here on instructables. For this instructable, all we need to know is that Oogoo is a mix of 2 parts silicone caulk and 1 part corn starch, and is three parts of awesome.
The aim of this instructable is to provide instructions on how to produce cheap Oogoo mixer to avoid the mess. The problem with mixing Oogoo is that mixing it in a cup makes it hard to scoop out, since it sticks to everything, also taking matters into your own hands will make things even worse (see the picture above). A solution to this is to use some kind of mixing aparatus, a really interesting one is proposed by doctek here on instructables, it is a 3D printed Auger press that evenly mixes the Oogoo, yet the clean up procedure looks messy, also my 3D printer is still in the works, so whats a guy to do eh? Go cheap, quick and dirty of course :) In the next steps i will explain how to mix your own Oogoo on the cheap, with simple, readily available or easily obtainable materials, while avoiding the mess all together.
Step 1: Tools and Supplies
For the mixer you will need:
1. A sirynge (desired mixing volume) X2;
2. Electric tape;
3. A pocket knife.
For the Oogoo mix you will need:
1. 100% silicone caulk (supposed to smell like vinegar, others don't work);
2. Silicone gun (my favorite XD);
3. Corn starch (i'll try experimenting with potato and other starches in the near future);
4. A teaspoon;
5. A funnel.
Step 2: Cut Off the Tops of the Sirynges
Use the knife to remove the tops of the sirynges. Don't worry about cutting clean, just get rid of them thats all, symmetry is not required either.
Step 3: Pull Out the Plunger From One of the Sirynges
Pull the plunger (the moving part of the sirynge) out.
Step 4: Join the Sirynges Together
Using the electric tape join the open ends of the two sirynges - the body of one sirynge without the plunger and the other with the plunger down. Make sure you wrap it around tightly upto about the half of the volume of each sirynge.
Step 5: Fill Half of the Volume With Silicone Caulk
Fill half of the empty sirynge body with silicone caulk, try to avoid air bubbles.
Step 6: Fill One Fourth of the Volume With Cornstarch
Using a funnel fill the quarter of the sirynge volume with corn starch.
Step 7: Top It of With Silicone
Fill the remaining volume with silicone.
Step 8: Reassemble the Plunger
Stick the plunger back in
Step 9: Mix
Step 10: Disassemble
Unwrap the electric tape to disassemble the "mixer".
Step 11: Extract the Oogoo
Squeeze out the Oogoo from the sirynges by pressing on the plungers,
The sirynges don't require cleaning and can be reused again. Also the tape can be replaced by
a flexible joint made from Oogoo, but that's up to you, i find it easier to use the tape.
And you're done, hope you enjoyed this tutorial, have fun with the Oogoo ;) see you next time.
