Farting Toblerone

Take one huge bar of Toblerone, and eat half of the chocolate. Replace the foil wrapped chocolate into the cardboard packaging letting it drop to the bottom. Seat yourself comfortably and turn the tube upside down to a vertical position and listen carefully

Giggle hysterically at the results.

Re-gain composure and serious look. Re-insert the chocolate and repeat.

The process is less reliable when there are only two triangles left.
