Whether you're looking to create a display item, a novelty gag or a prop for a play, realistic fake food spills are decidedly more convenient than the real thing. Fake food spills give the impression of being a big mess spread across the floor but consist of a single, clean and solid piece that's easy to pick up and transport. Create your own spills using a combination of casting resin and real and fake food components.
Locate or make dried food mixes that will combine well with casting resin. Best results will come from liquid and paste mixes with few large chunks. Good choices include powdered milk, powdered soups and sauce or gravy mixes. Set aside some large flake herbs, such as basil, parsley or red pepper flakes, to give the sauce some visual interest.
Gather solid food fragments to go with the liquid components. These are the dry components that will go stale rather than spoil, like cereal, bread or crackers. Collect any realistic fake food components you can find as well, such as decorative produce (fake grape bunches are especially convincing); you can often find these where housewares are available or in thrift stores.
Mix the resin according to the manufacturer's instructions in a disposable container (you will not be able to use it after this, except for mixing more resin).
Combine resin and food mixes in each of the appropriate food containers while the resin is still wet. Stir thoroughly with a disposable utensil (or any utensil you plan to incorporate into the fake food).
Arrange the fake food, real food and resin elements on plates as you would if you were serving them.
Organise the “spill” designs on waxed paper. Carefully tip the plates upside-down on the paper, and then slide the plates so that the spilt food smears and is visible. Arrange flatware upside-down in some of the resin. Tip the cups and bowls of resin gently, pouring out the resin in the most compact pool. Let the resin cure according to the manufacturer's instructions.
Glue down any loose food components with the glue gun, attaching them either to hardened resin, to the dishes or to other food pieces to make a solid, singular piece for each spilt dish.
Spray the dry goods with polyurethane or shellac; this will preserve them.
