Instructions
Find two straws of different diameters. Using scissors, cut the thicker straw one-inch shorter than the thinner straw.
Cut a hole 1/2 inch from the end of the straw. Squeeze the side of the straw. Cut a triangle shape halfway into the straw using a utility knife. The diamond-shaped hole is used to feed the fish.
Cut an eraser the same diameter of the thinner straw. Place the eraser in the straw to block the end.
Pour fish food into the diamond-shaped hole. Fill 1/4 of the straw with food.
Insert the thinner straw into the thicker straw. Push the thinner straw out to feed the fish. Retract the thinner straw to block the food hole.
