    um maybe ballistics or some kind of gel for the cytoplasm. it hods up its not leaky and that in a diff color would be great for a nucleus

    any store will have geloten powder here are the steps but dont worry allot of it isnt hard at all 1 get the gelatin Consider using plain Knox gelatin off the supermarket shelf. It cost approximately $10 US and will suffice for home usage. 4Mix a basic formula of one pound of gelatin powder to one gallon of water.(1/8 cup water per packet). 5You can also use the same amount of ingredients and just mix and cool! 6Consider mixing smaller batches one batch at a time unless you have extra large double boilers and spoons. By starting with smaller batches you can avoid wasting money should the larger batch burn, scorch or not set. The gelatin can also be mixed in two batches using 8 oz. of powder and 2 quarts of water. 7Measure out the cold water 8Add the gelatin powder all at once but stir it in carefully instead of dumping the powder. 9Try to moisten all of the granules without adding too much air. 10Look for a mixture that is the consistency of thick grits. 11Set the gel mixture in the refrigerator to chill and hydrate (a process known as “blooming”) for two hours. 12Set the gelatin over a pan of water (double boiler) and heated it until it is melted. 13Use a candy thermometer to make sure the gelatin mixture doesn’t get hotter than 130 degrees. 14Stir carefully to minimize air getting trapped in the gelatin and to disperse the heat. 15Use a mold sprayed with silicone spray to avoid sticking. The professionals use specially constructed 6” x 6” x 16” molds coated inside with silicone spray for easy release. Amateurs can use 32 oz. Glad Ware containers and non-stick cooking spray. 16Set the gel in the pan(s) to chill in a refrigerator for 36 hours before use. 17Carry it to the testing site in insulated containers 18Carefully unmold it immediately before testing.

    will the gelatin melt if you leave it out for too long without putting it in the fridge?

    regular gel will but when you make it this way in my case and can last a pretty long time. my advice is just bring it to school if your project has to be turned in later just put it in the fridge. it will certainly last longer than the car ride to school tho
