Using an extremely high voltage source (several million volts worth), it is possible to inject a a very large charge of electrons into a block of acrylic. Since acrylic is an excellent insulator, it will take many hours for the electrons to bleed off. However, a sharp blow with a grounded metallic point will (1) stimulate them to move and (2) provide them with an exit point to which to flow.
This is shown in the video below. As the electrons gather up into ever large streams, they heat up the acrylic and leave their mark as “frozen lightening”.
This is also known as a Lichtenberg figure.

There was a man wanted a boat more than anything. Despite all his best efforts, his wife was adamant in her refusal. Needless to say, he went ahead and bought a bought a boat without his wife’s approval.
"I'll tell you what," he told her. "In the spirit of compromise, why don't you name the boat?"
Being a good sport, she accepted.
When her husband went to the dock for the maiden voyage, this is the name he saw painted on the side: "For Sale."
Yes, there is advertising. The web hosting costs $5.95 per month and the domain name $10.45 per year (plus applicable taxes). Hopefully, the ads will, over the course of a year, pay for the cost of the website.
