I'm doing a science fair project.(what material absorb water.?
You might consider switching the substrate in the incubator to vermiculite rather then using moss. Vermiculite and perlite are the two main recommended substrates for incubation. They surround the eggs better and retain moisture reliably. Wet the vermiculite and then squeeze out as much water as you can by hand. The consistency that you are left with is what you want. Damp enough for the pieces to slightly stick together. I always incubate my corns with an a lid on the egg container with small air holes. There is often enough condensation produced to keep the medium moist through-out the incubation period but occasionally it does have to be re-moistened slightly. In that case lightly drip some water on the substrate in between the eggs. Don't wet the eggs themselves. The hatchlings should be separated from each other to avoid cannibilism and keep track of feeding. Deli containers are ideal, any take-out restaurant in your neighbourhood would likely be willing to sell you enough to house your clutch.
