Pour water, soap, glycerin, and corn syrup or sugar into a half-gallon Mason jar.
GENTLY mix together. Be careful when mixing your ingredients, or they’ll foam up in a major way! As eager as you may be to get to bubble-blowing, try to take it nice and slow with your mixing, and it will blend up before you know it.
Place a lid on the jar, and allow it to sit overnight before using.
To use, pour into baking pans and let the fun begin! This is a great alternative to bottles for tiny kids who dump the whole bottle before they even notice.
