Bob could not do the vulcan salute. Ever since he was a child he had tried and failed. 
Some kids could easily do it, but not poor old Bob. "How do they do it?" wondered Bob. 
He thought it must be very hard. "Indeed, it is very hard to do", thought Bob. 
One day, he saw a tube at a bike shop. The tube had "Vulcanizing Solution" written on it.
"Wow, finally a solution to how do to the vulcan salute!" thought Bob. 
With one hand, he squeezed the tube on 
his fingers of the other hand. He applied it on his pinky and ring finger on the area between them, and
did the same for his middle and index fingers. It worked - his fingers were stuck together in the right
way and and he was doing the vulcan salute! He thought it would be harder to do, but as it
turns out, it's easy once you know the "Vulcanizing Solution"!
