A spoon with no smoke?

Could someone please invent a spoon with a 2 way valve. When you inhale, the valve opens and allows the smoke in. When you exhale (BACK through the spoon) the valve closes and redirects the exhaust through say a small activated carbon filter? These 2 way valves are easy to get. They come on snorkels and on recessitation masks (sp?). The smoke would dissappear when it passed through the filter and be odorless.

I was brainstorming about getting away with smoking in public places.

 

Actually, with this idea, you're SUPPOSED to exhale back into the spoon. When you do, the 2 way valve CLOSES and directs the air to a different chamber. This chamber would have activated carbon in it. The activated carbon would filter all the smoke/odor out. And there would be no trace of the easily identifiable marijuana smell, unless the bowl you packed had a very strong scent.

You could make it more stealth too. You could have, what i call a "sealed bowl." (I have already designed). This would be something like a drawer in a dresser, or to make it more easily visualized, think about the CD tray on your computer. The sealed bowl comes out, u pack it with nugs, u push the drawer back in. Thus the bowl is sealed.

Wait a minute, wait a minute...How would you light it?

Good Question!
Answer:

The bowl would have either small holes in the bottom, or an internal lighter. The internal lighter is the best option, but it reduces the stealth of the pipe by making it bigger. The bowl would be at the lowest part of the pipe. This is because heat rises. The smoke is going to rise into the pipe instead of out of it.

Everyone knows that after u take a fat rip of your spoon, it continues to smoke. THAT smoke would be forced up and into the pipe. I know a lot of people who set their lighters across the bowl to stop it from burning anymore. With this pipe, you could just put your hand over it, and it would stop burning completely, saving your stash too!

I'll post some pictures that i made in Paint of what i'm talkin about after i get off work tonight. They are VERY VERY basic, but i think you'll be able to see what i'm talking about.

Think about it. I think it's a good idea. A stealthy way to smoke. And by posting it here, in public, i sorta am copywriting it. Now, everyone has proof of who had the idea/design 1st.

Here's a really crappy pic. I'm at work right now, so i have to be careful about drawing pictures of pipes on the company computers. Not to mention posting on this forum

 

The carbon work work great. The carbon would never be heated to more than around 100 degrees Fahrenheit (sp?). You would never touch the flame near the filter. And when you exhale the smoke would cool, inside the pipe, and then inside your lungs to near your body temp.
