ehosin asked if anyone knew where to buy the Oozinator. I located this at amazon for £17.50
However i've just come back from my local Tesco Home Plus store and they had loads of these reduced to £5 from £19.99.
These are not showing at Tesco Direct, and i doubt if they available in the normal Tesco stores - though worth a check i guess.
So, if you have a Tesco Home Plus store local to you go grab a bargain.
BTW 295ml cartridge of bio-ooze is supplied with the gun, though can use water as well.
