One day at the beach the water was very shallow at least 50 yards out. As we were walking out, not only did a dolphin swim within 20 feet of us, but we realized we were walking on hundreds of sand dollars! We gathered some up and took them back and had a fun science experiment learning how to dry and bleach them. We soaked them in fresh water…
Let them sit in a bleach solution for 10 minutes and dried them…
and then painted them with glue to help them harden.
We ended up with about 260 of them!
We now have them all in a bowl at home – pretty cool!
