It's got to be pies, although it's hard for me to explain why. Even from a young age before it was sexual I got a "forbidden" feeling about girls and pies. As I grew older, it evolved. Let's just leave it at that.
I suppose it would all depend on how easy the 'clean-up' would be.... An 'easy' clean-up out-doors; a creek, a pond, even a garden-hose would be a great way to clean-up. So the sky would be the limit !!!
But if you had to use your bathroom; tub, shower, etc., it would be a lot different.......
My personal favorites ??? Mud, pies/cakes/food, water-sports, and if it was the 'end-of-the-line' for your gear, paint, and used motor oil, so everything ended up gettin' torn and ripped up, so no need to 'clean-up' !!!
And to answer the second part of this question, 'Because it feels so good !!!'.......
It's MessySupplies' 'Clayzee Colours' Simply put it's the smoothest, thickest, most vividly coloured 'gunge' I've found to date.
How smooth? I use a plaster mixer in a drill and it's an easy smooth mix. Jazz cafe on a rainy afternoon smooth.
How thick can it go? Like thick mud- plunge a hand in and it'll squish into a vertical cliff around it. If you pour it out it'll splat down in big satisfying lumps. [It also mixes thinner too- makes for some excellent gunge pours]
How vivid? It's bentonite clay- making it fully opaque even in a thin layer, which makes the colour really intense.
It's also got the added bonuses of being pretty cost effective (£/Litre of gunge), and from my experiences it cleans off the skin easier than other gunges and has almost no taste/smell.
Custard has always been a fav of mine, you can use it warm or cold, mix it with other stuff like swiss rolls to make a thick mud like substance thats still edible, and its pretty much ready to go from the packet esp 1kg packets
i have been enjoying messy cakes alot lately, getting all dressed in the outfit i'm going to use, then going shopping for messy cakes and using them as soon as i get home, sometimes i dont make it home before i start!!
