(Sorry, phone camera again. I never remember to bring my nikon to work.)
The rice is SUPER simple! All you need is a bag of rice, hand sanitizer, and food dye.
I used the instant rice because it was what I had, and I used a 14oz box of it. I used 4 pumps of hand sanitizer (i don't think the amount is super crucial, just a blob of hand sanitizer to help distribute the foos coloring.). I used 20 drops of green food coloring, it could've used more if we wanted it to be really bold green. I put everything in a big zipper top plastic bag and shook it like crazy (the 6 year old loved to help shake it!)
Then I poured it into a big bowl (I did one bowl for each kid, but if you have a really giant bin, that could be fun too) with the gold chocolate coins! They liked to dig through with spoons AND with their hands! So much fun, pretty easy clean up too (just sweep up the rice!).
Happy St Patty's Day!!!
