Since my bong cooler only has a falling height of around 77 cm, I wanted to increase the surface area of water cooled and the time it stays in the air. Thus I decided to make add some "egg crate" kinda stuff to break up the water more.

After spending half a day with cardboards, duct tape and aluminum foil, I gave up on this prototype.

So, off I went to hardware shops to look for something that can work. Then I saw those rubber toilet floorings and these were just nice. I just needed to cut them to the appropriate size.

Now I had to stack these in the pipe. So, I decided to use chopsticks to support these stuff.

I drilled 4 holes for the chopsticks, 2 near the top and 2 near the bottom.

Silicone and duct tape to seal the holes.

I stacked 3 pieces of these on each of the 2 sets.

Now that this is done, I went onto refining my reservoir...
