Things You'll Need
Instructions
Seal off the bottle nipple with a dab of superglue and set it aside to dry while you're making the fake formula.
Measure 4 tablespoons of Bisquick or plain white flour into a bowl. Add 8 ounces of water.
Mix the concoction thoroughly, making sure all of the clumps of flour are dissolved in the water. The mixture should be milky but not too thick. If the mixture is too thick, add more water and stir again.
Pour the formula into the 8-ounce bottle. Check the nipple to make sure the glue is dry, and then pop the nipple back into the cap.
Trace a ring of superglue around the bottle rim and screw the lid into place. Allow the glue to dry before letting children play with the bottle.
