Bought a few pounds of water-absorbing polymer 'crystals' for the garden containers this year. Today I rehydrated the first batch. Ho-ly cow! Check out these before and after photos (I'll let you figure out which is which for yourself). One teaspoon of the polymer granules becomes about 4 cups of the rehydrated blobs! It's easy to see why they insist you should rehydrate the polymer before
mixing it with the soil (although it would be kinda cool to see a pot half-empty itself onto the floor as the polymer expanded!)
