Pop Corn Factory
This is one example of many similar effects you can perform with this box. If you wish you can transform sugar to sweets, rice to puffed rice, tobacco to cigarettes, 'flour' to 'flowers' etc.
Similarly you can change tobacco to cigarettes for a bar show or sugar to sweets for kids. Load compartment A and B according to your effect. Do not use spring flowers, as the spring action may prevent the flowers from dropping out. Use small size real flowers or buds and distribute them among the spectators at the end of the trick.
You can use a hat instead of a bowl if you like. If you use a Folding Top Hat you can show the hat empty very convincingly. The use of a soft hat is necessary if you wish to produce hard items like sweets or candy, as the soft inside will cover the noise of the production dropping in.
