Introduction: Oobleck Wallet
self defense(throw it at someone)
I got a video!
Step 1: You'll Need
food coloring if you want
Step 2: Oobleck
most websites say use 1 to 1.5 times more cornstarch than water, I used about twice the amount but you should experiment
by adding cornstarch to water while stirring
this is the stuff that gets hard if you hit it hard so don't stir it hard, or pour it down your sink
to make it cooler you can add food coloring
Step 3: Almost Done
put the oobleck in the bag, but a little less than half full, squeeze all the air out, tape the top
Step 4: Finish
make a sheet of tape, put more tape on the sticky side except for the bottom and sides, stick it on, now it's a coin holder
fold it in half, tape the sides and you're done
We have a be nice policy.
Please be positive and constructive.
