Re: Plaster Cast Hands!

<<Is it really necessary to fill up with plaster immediately?
Do you know if it can wait overnight?>>

I don't know if it's necessary to fill with plaster immediately or not.....
I don't think the mold would dry out so much to make the plaster stick to
it--just haven't tried, and the kids are so eager to do this that I haven't

I ordered the first small container from a dental supply company and then
ordered the big container from Douglas and

I was totally blown out of the water when I saw the casts being produced at
the art camp last summer. You literally could take fingerprints from the
hands that the kids were getting out of the molds!

Obviously, you have to be careful about the position of the hands in the
mold--if fingers are "hooked" there's a chance that the mold will be damaged
when the hand is removed, and also there's a possibility that the plaster
will not fill those sections.

Another thing to consider is that kids with big hands might have a problem
keeping away from the bottom and the sides of the cup. If I could think of
a slightly wider container to use, I might consider it--especially if we try
something other than their hands....

But all things considered, it's a neat project. Certainly not a whole lot
of work or skill required on the part of the students, but something fun and
impressive, nonetheless!
