Is there a way to make a sand-castle mold so that it can be used over and over again?

Yes, you can make a sand-castle mold by using silicone caulk. First, you need to create the shape of your castle in the sand. Then, use silicone caulk to fill in any gaps between the sand pieces and smooth out any bumps or uneven surfaces. Once you have filled in all the gaps and smoothed out the surface, let the caulk dry for 24 hours before removing it from the sand. You can then use this sand-castle mold repeatedly.
