for any ameroid that didn't instinctively know what a "water butt" is, it's apparently what they call drums/barrels for rainwater catchment in gardening within the UK. could be wrong, because i just learnt this.
if you search it, you can see all the fancy, modernist and metropolitan shapes they are sold in, unlike the US where we all seem to have those same 50 gal ones that are like bright blue or white and probably leach PBAs or whatever and would require like 3 stout men to lift when full and one of them would have to go lay down for the rest of the day.
a water butt is not a butt that squirts water.
