Water balls are unlike your usual magic trick that only allows you to watch from afar while another person holds the object and makes it disappear. Although they are not exactly solid objects, water balls make for an entertaining trick and illusion. Water balls are not made from agar or silicone gel, a common misconception. A solution made with a hint of salt, sugar and baking soda is what you need for the water balls. The process is not very complex and will take less than an hour to complete.
Add 28.4 g (1 oz) of salt, 14.7 ml (1/2 oz) of vinegar, 1/8 tsp of baking soda and 14 g (1/2 oz) of sugar to a plastic mixing bowl. Mix the contents thoroughly with a spoon until all ingredients are evenly distributed.
Place your mixture inside the freezer for exactly 10 minutes.
Remove the mixture from the freezer and mix it with your spoon until it is evenly distributed.
Bring out your pan and place it on top of your stove. Turn the stove on medium heat, and let the pan sit there for at least two minutes, or until it is well heated.
Add the contents of your mixing bowl into the pan and wait until it comes to a boil. Turn off the stove as soon as the mixture boils. Set the mixture aside for 10 minutes and allow it to cool.
Add 237 ml (1 cup) of water to the mixture and mix it well using your spoon. Place the mixture back into your mixing bowl and put it inside the fridge for at least three hours.
Remove the mixture from the refrigerator and start playing with your water balls by dipping your hand into the mixture and pulling out the tiny beads.
