HELP I have a project in honors bio for cells(animal cell). I wanted to make a 3D model by carving a large foam globe in half and rilling a 3in indention in one of those haves with clear Elmers glue. Will it work? i was going to make the inside parts out of clay and have them protruding out of the cell. The problem is i don't know how long it will take to dry and if it will stay the same shape. Also will the glue eat away at the foam like resin? I can't use resin because of the price and I was put on a limited money by my parent. THis is due on the 19th of September and i need a answer by tomorrow due to me going shopping. Thank You for your response.
