However, Kiera Wilmot has probably shaken her head enough lately and will now be grateful for a little stillness.
Should you have been unaccountably arrested for expectorating in your high school cafeteria recently, you might not have heard about Wilmot.
One morning at Bartow High School in Florida, she put toilet cleaner and aluminum foil in a water bottle to see what might happen. It was just, she said, an experiment.
Even her school principal admitted that it merely sounded like a firecracker.
However, she found herself expelled from school and arrested for felonious possession/discharge of a dangerous weapon.
It emerged that the same D.A who charged her had, two days previously, decided not to charge a 13-year-old who shot dead his 10-year-old brother.
However, now there is some good news. Or, at least, sane news. The criminal charges have been dropped. She will not have to live her life as a felon.
