Best Bong Precoolers
The best bong precooler would be the one that is most effective at achieving the job that they were designed to do! So let us take a look at the main reasons why you would want to add precoolers to your bong.
Reduce Tars in your Smoke: Passing smoke through water and running smoke over glass is a great way to remove tars from your smoke.
Cool your Smoke: The more water the smoke has to pass through, the smoother it will be.
Percolator Bongs for further tar removal
I know for a fact that everyone would love the effects of percolator bongs. If you really are serious about being a cool stoner and want to be healthy at the same time then check them out; http://www.herbtools.co.uk/bongs/percolator.html
So these are the main two reasons, so that tells us we want a large glass precooler as this will be best at achieving the two points above. The fun doesn't have to stop with just one precooler, if you find the best precooler you could actually buy two of them and stack them! A cooler for your precooler, if you like!
Removing extra tar from your smoke is something I strongly recommend, so adding a precooler will make your smoke sessions a little safer for you.
