Hey all,
So my gf and me are planning on getting messy again this weekend but instead of pouring stuff on each other I wanna fill the tub with something and play around in it. What has everyone had success with being easy to wash down the drain? Keep in mind she likes sweet stuff. Also if you have a rough idea of how much of it will be needed to fill the tub that would be helpful as well!

Ditto on this.

I will try something soon, but thinking I'll have to bucket it down the toilet. :/

About 100 litres.

Disposal depends on what you're using. Food, with all its oil and lumps, should go down the toilet (gradually!) but this may still block.

Sieve out the solids and flush away the liquids. Bin the solids in food recycling (compost) or double bagged in the rubbish.

Yes. It's a faff!
