no! that recipe is crazy......
the proportion of water:acetone is just around half and half, but you can go less too.
ok, here we go:
1. empty 1 pack in to a glass OR metal container
2. pour in near boiling water
3. pour in almost equal amount of acetone. the water will boil a second because the acetone will lower the boiling temperature...
4. wait till it stops churning. it won't take long
5. submerge your plastic
6. when it reaches the shae you want, take it out and wash it in cold water
7. set aside so the plastic can cure again
a couple things to consider
1. acetone isn't good for your health, at all. please wear gloves and a mask, and preferably do this outdoors (if its not too cold)
2. you may find methods online that tell you to stick this all in the microwave. ignore them.
3. use something not too hard to get the plastic out of the acetone, because the top layer of plastic will be very soft. you can dent and scrape it then until its cured.
i hope this somewhat helps out... honestly, i wouldn't start out with but 2:1 water:acetone, until you learn what is going on. it took a bit of effort for me to be able to get a nice result from this. i melted a few.
and, the instructions for yo-yo dying online are a good place to start, but the plastic is generally different from the harder plastic used in yo-yos.
i'm blabbing. let us know how it works out...
i forgot a couple more things...
1. do NOT inhale the rit powder. you'll have brightly colored boogies for a few days (i thought something was seriously wrong with me when i sneezed up black after doing this without a mask). the powder is very small, and easily catches wind drafts...
2) MIX WELL! if the rit is clumpy in the water at all, it'll show up on the plastic
