Re: Plaster inside Balloons

The best way I have found is to dilute the plaster a little more, and squeeze
it through dishwashing soap bottles into the balloon. Then, for eggs, I
inflate the balloon some, and tie shut and float them in water for even
pressure, spinning them once in awhile. For rocks you could take them out when
they start to harden and smush them around a little.
