It is very important to use the right nozzle when inflating a Double Bubble Balloon with helium in order to get the best results and float times.
A Double Bubble Balloon requires a lot of pressure to inflate and only a latex regulator (rubber tip) can get the job done. Do not use a foil auto shut-off regulator (brass tip), because it will shut off before the bubble balloon is completely inflated, and your Bubble Balloon will look like a foil balloon.
Use the rubber latex regulator and be careful not to damage the valve when inflating the Bubble Balloon.
When inflating with helium:
- Inflate all balloons with helium.
When inflating with air:
- Inflate all balloons with air. Do not use both air and helium for the same balloon.
How to Inflate a Double Bubble
1. Look for a blue valve (A). Inflate the outer bubble slightly with a latex regulator, so the inner balloon will have space to inflate.
2. Locate the white valve (B). Inflate the inner shape fully with a brass foil regulator.
3. Use both hands to move the foil balloon into a good position.
4. Return to the blue valve (A) and inflate the outer balloon with a latex regulator, until it is round and free of wrinkles and bumps.
If the inner balloon shrinks while inflating the outer balloon, return to the white valve (B) and add a micro-second of helium using a latex regulator. You can also use a hand pump to add just enough air to fill out the inner balloon.
