When I lived in Kentwood, Michigan there a pole in a local park with a sphere on top, the top half was yellow of the sphere, and the bottom half orange, about 3 meters off the ground. It would take about 8 pulls to get to the top, with rain I would have to dry the pole off as I gripped with my knees to slowly climb to the top. Snowfall was no obstacle to climbing, but ice from heavy frost, misting, or an ice storm totally blocked climbing. This means that van der waals bonds from the hands and pants or bare knees upon squeezing permitted a pole to be climbed. Somebody suggested a green pole in a green room to produce the illusion of levitation. For class pole climbing, it needs a hose nearby so once a pole gets climbed, the same individual must climb a soggy pole by drying it off to fully demonstrate the same van der waals bonds that allows insects to scurry across walls. It would take a 40 tesla magnet to levitate a person by paramagnetism to equal climbing a dry pole.
