Joust has developed their own Squeeze Whistle. This type of whistle was developed to minimise the transference of saliva based germs.

The Squeeze Whistle is surprisingly easy to use:

1. Get Squeeze Whistle.
2. Open Hand.
3. Place Squeeze Whistle in open hand.
4. Close hand.
5. Open Hand again.
6. Repeat points 4-5 as and when sound is required.
