Bag Of Lights

Performer is seen holding a paper bag. 
He reaches into the air and plucks out a red light and drops the light into the paper bag. 
The light can be seen falling into the bag and settling at the bottom. This action is repeated 6 more times for a total of 7 lights, all seen floating at the bottom of the bag. 
On the command of the performer the lights are seen to float up out of the bag and reappear in the performers hand, or vanish. 
This is a custom made and programmed electronic prop. It works itself  literally "at the press of a button" !
