## Questions & Answers

**Q: Do you need to prep these to get the air through**
A: Yes you do need to it and it can be sorted out in two ways, first, you can soak them in water for 24-48 hours and water will get inside . But i use a pipet from one of the medication bottles that i have left over and then you can put the water in and use them straight away.
