I am planning a future messy session. What are some of the favorite items to use? I am thinking of both easy cleaning (non chunky so it washes down the drain) or other items if we do an outdoor session (no restrictions). I don't really care about saving the clothes. In fact, total destruction/staining of my jeans/tshirt/polo shirt/dress shirt etc may be encouraged. Items that come to mind include: paint, markers, eggs, yogurt, tomato sauce, ketchup, mustard, grape juice, soda, real pies, shaving cream pies. We will be pouring both on and inside the clothes.
What am I missing? Any suggestions or tips for what Not to use? Thank you for your input.

Judgin' from your previous pixs, I think you know what to do....... Real, (edible...), pies would be my recommendation. Just have some fun doin' it.....
