Good Morning America Now Steve Spangler explains the 4-H National Science Experiment
As part of the 4-H National Youth Science Day, Steve Spangler
made a visit to ABC's Good
Morning America Now the first week of October, 2008.
Developed by Steve Spangler and his team of experts, the National
Science Experiment teaches kids about hydrogels and the role
that these polymers play in conservation. A hydrogel is a
superabsorbent material that grabs on to water molecules very
quickly and soaks them up. Hydrogels have many common uses,
including the material that is found inside of baby diapers.
Hydrogels come in many different forms. Steve and two 4-H members
demonstrated Water Gel, Water Jelly Crystals, Clear Spheres and Insta-Snow for GMA Now.
Farmers use hydrogels, like water jelly crystals, mixed in the soil
to help with water conservation. The hydrogels absorb a large
amount of water that can water plants without the heavy use of
sprinkler or watering systems.
4-H members across the country performed the Baby
Diaper Hydrogel Experiment for 4-H National Science Day.
