Dehydrating Potatoes

check out the pencil!

Unfortunately, we buy honking big Idaho Russets, and it took a full 36 hours to shrivel as advertised. When we repeated the experiment with a small red potato, it only took an hour.

This book has some really great ideas, catalysts for actual experiments, but I think their fact checking was completely absent. Their "raw or boiled?" egg experiment, for instance, was completely backwards. Thank goodness this Mom knew better beforehand!
