Cup-O-Flies system includes the 6" container w/mesh lid and 3 portion cups & water crystals. .Also now comes with sample food. Use one cup for the pupae, one for the food that is alredy added and one for the water crystals. Take a few crystals maybe 8 to 10 and put in portion cup and add a little warm water. When crystals are fully grown discard any extra water. This is now ready for the flies to suck the water off of with no chance of drowning.
