Planning for wild and wacky art camp gets complicated

I always want something new and different to excite and entice but keep getting asked "what about the volcano? are we doing a milk thing?" Guess there is a desire to do the familiar and fun too. We are going to try some new stuff this year like building a structure with crafts sticks to see how well we engineer and some old stuff like making a kaleidoscope, using materials in a new way painting with crystals in solution, and experimenting with the movement of color through materials. The younger set gets to explode paint and make a new kind of clay and everyone gets a try at luminescent paints. Just my thoughts.
