While working on my project (picking snails), I came across a super, time-saving invention. Featherweight forceps. These are tweezers made of super thin spring steel, which allow me to pick up snail shells without crushing them (even the tiny Vertigo shells). In addition, tweezing them takes a fraction of the time the old "moist brush" method would take. Meaning I can get snails counted in less than half the time it used to take me. Highly recommended for the tiny bug-picker in your family.
These are from Bioquip's website, but I've also seen them offered in Fischer Scientific and other places.
