How Make gravity Bong?

How do I make a gravity bong. I've read about them for years, but have no clue.

there are plenty of threads on this...look it up

If you want to make a gravity bong, try getting a bucket of water. Then get a big gatorade bottle and cut the bottom off. Next, drill a hole in the top of the cap and find something you can stick in it to use as a bowl. Then just put the gatorade bottle into the water, cut side down and push it down into the water until the bottle is filled almost to the bowl. After that just load your favorite bud and then hold a flame by it while lifting the bottle out of the water. The vacuum created inside the bottle from the water should pull air down into the bottle thus lighting the weed and filling the bottle with some. Next, remove the cap, cover the opening of the bottle with your mouth and push the bottle back into the water. Viola! Gravity Bong!
