How long does it take a sand dollar to turn white?
my mom and me do sand dollar art and we found out after we got our first sand dollars,they turned yellow,then we went to a shell store and we found out we need to get some bleach,and we soaked them in a bucket of bleach,so they could turn white.so what you need to do is soak them in bleach,they won't do it by them selves.
I remember being in Florida one spring and we found alot of sand dollars that were alive. I don't remember anything happening when we picked them up.
However, if you held them too long they might make a little change in your hand.
once they dry out they usually are ok till someone drops it [ someone always drops it ]... once its dry paint away. i've seen some nice beach scenes painted on sand dollars. some types of sand dollars have the image of JESUS on the cross on the back .. check it out.
