They saw a lifelike rubber left hand in front of them. The experimenters stroked both the subjects hidden left hand and the visible rubber hand with a paintbrush. The experiment showed that if the two hands were stroked synchronously and in the same direction, the subjects began to experience the rubber hand as their own.
A cork borer, often used in a chemistry or biology laboratory, is a metal tool for cutting a hole in a cork or rubber stopper to insert glass tubing. [1] Cork borers usually come in a set of nested sizes along with a solid pin for pushing the removed cork (or rubber) out of the borer.
A laboratory rubber stopper or a rubber bung or a rubber cork is mainly used in chemical laboratories in combination with flasks and test tube and also for fermentation in winery. [ 1 ] [ 2 ] [ 3 ] Generally, in a laboratory , the sizes of rubber stoppers can be varied up to approximately 16 sizes and each of it is specific to certain type of ...

Rubber tapping in Indonesia, 1951. Rubber tapping is the process by which latex is collected from a rubber tree.The latex is harvested by slicing a groove into the bark of the tree at a depth of one-quarter inch (6.4 mm) with a hooked knife and peeling back the bark.
The Daily Planet's The Greatest Show Ever, [10] ran a competition whereby five Canadian science centres competed for the best science centre's experiment/display. Edmonton's Science Centre (Telus World of Science) utilized a Rubens tube, and won the competition.
Rubber elasticity is the ability of solid rubber to be stretched up to a factor of 10 from its original length, and return to close to its original length upon release. This process can be repeated many times with no apparent degradation to the rubber. [1] Rubber, like all materials, consists of molecules.
Rubber cement (cow gum in British English) is an adhesive made from elastic polymers (typically latex) mixed in a solvent such as acetone, hexane, heptane or toluene to keep it fluid enough to be used. This makes it part of the class of drying adhesives: as the solvents quickly evaporate, the rubber solidifies, forming a strong yet flexible bond.
