Gunge as it is known in the United Kingdom, or slime as it is known in the United States and most English-speaking areas of the world, is a thick, gooey, yet runny substance with a consistency somewhere between that of paint and custard. It has been a feature on many children's programmes for many years around the world and has made appearances in game shows as well as other programming. While gunge mostly appears on television, it can also be used as a fundraising tool for charities, youth and religious groups. Gunge tanks have appeared at nightclubs and Fun Days. The British charities Comic Relief and Children in Need, supported by the BBC, have used gunge for fundraising in the past. In the U.S., slime is sometimes associated with Nickelodeon, even having several game shows revolving around it, such as Slime Time Live.
