First of all, check your Groupon account to make certain you’ve got everything you wanted in there…then go over to American Scientific’s site so the fun can start!  There’s so much cool stuff there you can get lost in the black hole of science.  See the Sharper Image mini camcorder (3-1/4 x 2 x ½) for $39.95 or the electric sign or the practical Havelock cap…learn something new every day, folks…
