1
Position the nozzle of the squeeze bottle just above the surface of the bowl of water at about a 45 degree angle.
-
2
Direct a stream of water toward the bowl. Don't squeeze too hard--but don't squeeze too lightly, either.

With some practice, you will see separate globules of water land in the bowl. If they float for a while before popping, use a bit more force in squeezing the bottle, and the antibubbles should sink beneath the surface of the bowl.

If you decide to try the medicine dropper instead, hold the dropper above the surface of the water at a 90 degree angle. Use droplets instead of a steady stream of water. This method seems to have more success, but also tends to result in smaller antibubbles.

Tips & Warnings
Making antibubbles takes patience! Success is based on different factors, so keep trying. Antibubbles may be difficult to spot. They tend to be somewhat lighter than the surrounding liquid. If you add food coloring to the water in the bottle/dropper, the antibubbles will be easier to see.
