FUN STUFF
Make an Edible Candy Landfill
Items Needed:
- Clear Bowl (serves as the landfill "cell")
- Marshmallows (fabric layer)
- Fruit Roll-ups™ (liners & "cap")
- Chocolate Pudding (dirt)
- Licorice (leachate collection)
- M & M’s™, animal crackers (garbage)
- Smarties™ (pea gravel)
- Sugar Wafers (drainage layer)
- Green Sprinkles (grass)
- Spoon (to eat with!)
Step #1
Line bowl with fruit roll-up™ (liner). Liners seal garbage and leachate (any liquids) in the landfill.
Step #2
Cover the fruit roll-up™ with a layer of sugar wafers (drainage layer). The drainage layer collects any leachate passing through the leachate collection pipes. Leachate is pumped to a treatment plant.
Step #3
Add a second fruit roll-up™ (liner) over the sugar wafers.
Step #4
Add a layer of marshmallows (fabric layer). The fabric layer cushions the bottom layers from punctures.
Step #5
Sprinkle some of the smarties™ (pea gravel) over the marshmallows. Pea gravel filters leachate into collection pipes for treatment.
Step #6
Tear licorice (leachate collection pipes) in pieces the length of the bowl and lay in rows over smarties™. Leachate collection pipes collect leachate and pump it to a treatment plant.
Step#7
Add remaining smarties™ (pea gravel) on top of licorice.
Step #8
Place another layer of marshmallows (fabric layer) over the smarties™. This layer cushions the layers below from any sharp objects that may be contained in the garbage.
Step#9
Dump a layer of crushed animal crackers and M & M™’s over the marshmallows. This layer represents assorted garbage.
Step#10
Cover with a thin layer of pudding. Each night, the garbage in a landfill is covered with a layer of material (usually top soil). This layer reduces odors and litter problems.
Step #11
Alternate crackers and M & M™’s (assorted garbage) with pudding (dirt) until layers are 1 inch from the top of the bowl. Top it off with a layer of pudding (dirt).
Step #12
Sprinkle another layer of marshmallows (fabric layer) over the pudding. This fabric layer protects the top layers from sharp objects in the garbage below.
Step #13
Unroll another fruit roll-up™ and place on top for the "cap". A cap protects the landfill from rainwater. This reduces the amount of leachate entering the landfill and flowing into the leachate collection pipes.
Step #14
Add a final layer of pudding (top soil) and top off with candy sprinkles for grass (final cover to prevent erosion of top soil).
Unlike a real landfill, you can EAT this one! DIG IN!
