Rub out splinters with a pumice stone
SiloDog's splinter removal hack should come in handy during these barefoot backyard days:
Next time your little ones have splinters in their hands or feet, try this: Let them soak well in the bathtub, then use a pumice stone (like you would for rough heels or elbows) to rub over the splinters in a circular motion before they dry off. They can even do it themselves. It seems to work for those playgound / deckrail splinters pretty well.
I've never tried this myself, but it seems like a good solution for those tiny splinters that hide in certain types of bark mulch.
