agree with Jade. Looks better on the tv than reality. I bought as a special treat as it is expensive at £5 per box (and each box is enough only for 6cm of water). The stuff didn't look anything like on tv advert - more like very runny wallpaper paste. Dissolver didn't dissolve properly either. Kids thought it felt horrible. Not sure where the "fun" element came in. Won't be buying again.
