Pig bladders were used in the 19th century to store an artist’s paint. The bladder would be sealed with a string and then pricked to get the paint out. This option wasn’t the best because it would often break open. American painter John G. Rand was the innovator who made paint tubes from tin and screw cap in the 19th century.
Surfboard wax (also known as surfwax ) is a formulation of natural and/or synthetic wax for application to the deck of a surfboard, bodyboard, or skimboard, to keep the surfer from slipping off the board when paddling out or riding a wave. It is also used to increase grip on the paddle of a surf kayak or dragon boat.
