Flash

A Flash means throwing and catching each prop once, usually from a cold start and to a collect. Going into 5 throws of a 5 ball trick from a warm start and back to the basic pattern afterwards would also be called a flash. The highest numbers of props that have been flashed are 13 balls by Alex Barron, 13 rings by Albert Lucas, 12 ball bounce by Alan Sulc, 9 sticks, and 8 standard clubs.

High flash

A flash can also refer to throwing all (or most) of the props being juggled higher than the basic pattern so that both hands are briefly empty (unless not all were thrown high). Both meanings of "flash" can be used as either a noun or a verb (e.g. "a three ball flash"; "flashing three balls"). A high flash can be used as an exercise to prepare for learning a higher number of objects. You should have time to clap your hands together while the objects are in the air, but the clap is not a necessary part of the exercise as long as you know you have enough time that you could clap. Other things such as 360s, 720s, or backflips can also be done while the objects are in the air after a high flash.
