The children start clapping their hands and the “mercury” of the Klapp-O-Meter rises. When the sound of the applause decreases, so does the “mercury”. When the clapping reaches its climax, the “mercury hits the ceiling” and the Klapp-O-Meter explodes and paper streamers fly up in the air.

This has been the opening number of my family shows since the early 1980-ies. We put out the effect in 1983, it sold out and has not been available for over a decade, but now it is back! A great warm-up routine for family audiences!

Both Trevor Lewis and Patrick Page have told me that they invented the Gag Applause Meter, well this is our version.
You will need Party Poppers, available from toy and jokes shops, for the explosion feature. Quality prop, silk screened on durable PVC plastic.
