2. The slipperiness comes from the follicle cells on the inside of the peel. When they are crushed underfoot, they release a polysaccharide gel between the floor and the peel.
3. This gel is so slippery, it is actually a better lubricant than the oil used in metal bearings. It’s only slightly less slippery than a ski on snow!
4. Polysaccharide gels are also found in the membranes covering our bones at the joints. Research into banana peel slip-ups is helping to improve the design of joints in prosthetic limbs.
