What Am I Talking About?

If you answer one correctly, you get to offer ones of your own:

[list=A]
[li]a dormant global twist, induced by random movement, encountering a metastable knot-antiknot pair, causing an abrupt change in torsional energy[/li][li]226.4 chirps per minute by a snowy tree cricket[/li][li]a capsicum with a mean percentage level of 18.36 percent oxygen and 1.15 percent carbon dioxide[/li][li]widely spaced grooves around the cannon shots, and clearly visible — almost right-angle turns — in the grooves of the shots themselves[/li][li]a rattling of a randomly magnetized color mask and other ferous metalwork caused by a strong surge of current through a large demagnetizing coil[/li][/list]
