I am doing an activity with my students and need to figure out how big of a bag of plaster of paris I need to make the handprint craft where the children each put their hand in a plate of plaster of paris. Any recommendations of how much to make to make 30 handprints?

most craft stores sell it in large bags that you can make up in batches. that way you can always make more if you need to, which is better than having to mix a whole bag at once and having a bunch left over.
I just did my daughter’s hand print and used about 1 cup total. It really depends on the size plate you are using.
ok the problem is the plaster sh-inks,when it drys
so i would guess about , three bags of 25lbs would work
if you only mix what you need, you wont waste it
so try with a small load and time it , before it goes off,
and its fast ok …….
