Now, if you do the math you'll figure out that Moon Sand is roughly
$2.50 per pound on sale, down from $4/lb. Not bad, but not great. With
the following recipe you can create around 50lbs of homemade moon sand
for $30. That equates to 60 cents per pound, over 4 times cheaper than
the sale bucket! So, grab your rubber gloves and lets get to work.
