How to build (relatively)

Perfect for cleaning or removing tonches between teeth and braces (tonsil stones).

Screw the bushing into the hose adapter and screw the rewind into the pipe of the required length (I used about 3 ')
Insert the inverted hook into one end and fine the outside of the other end with a knife so that it can fit into the inflatable needle. Wrap the inflatable needle around the needle and leak the needle into the hole on the side to prevent the water from flowing out in both directions.
