The “MARS LANDING SURVIVAL KIT” from WILD! Science is true Space Age Science. No, it is NOT A TOY! Plant your first seeds in Bare Sand enriched with Hydrogel Crystals. Yes, the Digested Waste is totally gross, but the Biodome Hydroponic systems and Capillary Filters turn it into clean Plant Nutrients! As the real plants grow, they absorb poisonous CO2, and make OXYGEN you can breathe, FOOD that you can eat and PURE WATER by transpiration! Any leftovers go back to the Waste Digester and the cycle starts again. You can even Clone plants! The lab gear – is real. The GAS, WATER and UV Testing Indicators are real. And the FUN is out of this world. Hours, weeks and months of EXPERIMENTING AND FUN!
