Hellman's Mayonnaise is thixotropic, as is latex paint, which exhibits spatter mist caused by the breaking of elastically fluid strings formed by separation of the roll from the coated surface. The same phenomenon is seen in the behavior of the adhesive of ScotchR tape when it is stripped from a rigid substrate.
Odd, but true.
Laser fusion was attempted a number of years ago by employing hydrogen-filled tiny millimeter-sized glass spheres dropped one by one into the center of, and bombarded at, the juncture of the beams of peripheral lasers, the beams impinging normal to the sphere's circumference.
I wonder why they went to a metallic containment instead? (Perhaps because the glass is elastic only up to the point of fracture, whereas a metal suffers significant integrity in plastic elongation after the elastic limit is reached?)
Skip the messy mayo and the expensive lasers.
Some types of tape and a bit of luck will produce triboluminescence, a pretty blue light.
Just stick them together and quickly pull them apart, in the dark.
Very low budget and ultra-low power output, but you can do it at home.
Sometimes in these threads MY limit gets stretched quite a bit!
It has even SNAPPED before!!
