You can get a blown-up balloon from anywhere.
You can hide the blown-up balloon in your hand or in your wallet and then get it out, intact and undamaged.

Air from the balloon can pass through your ears into another balloon.
• The device is compact and lightweight

• You can control the blown-up balloon without using your hands.

 Your hands are free during the performance. You can turn the blowing on or off at any moment, unnoticed by the audience.

The rules for the use and service of the batteries:
If you do not use the device, you have to once a month, fully discharge the device and charge it again. If you do not do the battery maintenance, the device will break. 

• Runs by electricity.
• The weight of this prop is about 450 g.

Examples of other effects:

Imagine the magician chewing a gum and blowing bubbles and afterwards turning the chewing gum into a blown-up balloon, which he gets from his mouth. Then he swallows a balloon back and turns it into a chewing gum. Imagine the magician, after completing swallowing a balloon reaching into his mouth and slowly starting to pull out a blown-up balloon! If you don't perform the swallowing balloon - no problem - be different by reversing the sequence and producing a blown up balloon from your mouth (it's a lot easier to learn too!). Either way you do it - it will get a big reaction.
