I had some TOBS cream and a spare wooden bowl. Preferring the look of a nice wooden bowl to the TOBS plastic tub I transferred the cream across. It's been in this bowl for some time now and appears to have reduced in size somewhat by drying out. It looks to me like moisture has been lost from the cream in to the bowl and out in to the atmosphere. Is this a normal phenomenon that is widely know by most except me? Could this be the reason TOBS package their cream in plastic tubs? :?
