So I sealed off this Syringe with a match

Those things doctors draw blood with. I have one with a curved, plastic needle that I'm suppose to use to squirt water in the back of my mouth to keep my Wisdom Teeth cuts clear of food. Well, I sealed it off by melting the tip with a match, and now there's a pseudo-vacuum inside.

When I draw back the handle thing, throw it into the air and let go, it flies in the opposite direction that the water should come out of.

Why?

You sealed off the tip and heated up the air on that end. The oxygen molecules that were compressed in that area got heated up and started moving around violently from the heat. Therefore the air needs to escape and when you draw back the handle thing, it tries to escape from that end and flies in that direction. I think :<

As you said, there's a pseudo-vacuum; it's not a true vacuum. You sealed the needle but you did not seal the plunger, so air can still pass into and out of the syringe from the plunger end. When you draw back the plunger, you increase the volume of the syringe. Ergo, one or both of the following events must take place:

1. The air has to rush in to fill that volume. The only location at which it can do this is through the plunger end.
2. The volume has to restore itself to the surrounding air pressure, since you lowered the air pressure by drawing back the plunger.

The volume of the can't restore itself instantaneously, so before it does, air rushes into the syringe. This produces a force that causes your syringe to fly in the observed direction.

Off topic: My doctor gave me penicillin instead of a syringe.

How would penicillin remove the particles of food that may get stuck inside & around the wound site?

It doesn't. Rinsing with water and watching what kinds of food I eat does that. But if food does get stuck there, the penicillin prevents infection and the medrol prevents swelling.

Huh. I just got my wisdom teeth removed this past Wednesday. I've been taking penicillin, ibuprofen, and Tylenol 3. (Not all at once, of course.)

How does the the penicillin and the medrol reach your gums? Do you take digestable pills and then the drug is specifically oriented to reroute to your mouth? I couldn't imagine simply relying on rinsing to rid myself of small food particles that could be leftover in my gumline and possibly getting stuck in there when new teeth reform.

Antibiotic and two over the counter painkillers. Tylenol usually contains acetaminophen with no trace of aspirin or caffeine. In comparison, Anacin contains aspirin and caffeine & Excedrin contains acetaminophen, aspirin, and caffeine. Theoretically speaking, the Tylenol is like the icing on the cake. If I recall correctly, ibuprofen is used to reduce swelling because it is a steroidal anti-inflammatory drug. The Tylenol would probably help post-pain after the wound has healed since it cannot help with swelling.

hah, all you pansy's. ive still got all but one of my wisdom teeth. only reason i had one removed was because of a cavity.

Just make sure your teeth aren't impacted. My dad didn't know any better and the dentist had to drill right through two of his wisdom teeth before smashing them with a hammer.

You pansies. I was born with no wisdom teeth.

Just as I said with TobiasBlack, you should double check with a dentist and make sure that you don't have any impactions. If you have the potential to develop some, then you should get them removed. If not, then you should die in a fire.

You pansies. I was born with no wisdom teeth.

Same here, bro!

Die.

ive had them since i was 17, only problems with the one.
OUTLOOK IS GOOD BRO, IMA KEEP EM ALL. OF ALL THE THINGS I INHERITED FROM MY MOTHER THE BIG MOUTH IS THE ONE PERK FOR THIS REASON ONLY.

Actually, on the bottle of the Tylenol that I've taken, it says, "acetaminophen-caffeine w/codeine". What exactly would caffeine help with, anyways?

And @Tobias: Wouldn't removing one of your wisdom teeth be bad, since the tooth it's normally supposed to bite against will have no partner?

I think you should be more interested about the codeine.

Codeine (INN) or methylmorphine is an opiate used for its analgesic, antitussive, and antidiarrheal properties.

Oh.

No, but what would caffeine help with? I mean, did you mention caffeine because it helps treat the pain somehow?

Oh. No, but what would caffeine help with?

Fending off headaches. Probably.

my jaw's already got issues, so the wisdom tooth thing isnt an issue.

I think I was holding it wrong. It now shoots forward like I would expect it to when the rubber slams into the base. The dog was not as amused as I was.

You guys are lucky, my doctor gave me half a dozen of some pain med that ran out Friday. An Advil here and there has been my only escape from the pain. :[ I had all four taken out, but only the bottom left sore has caused my any discomfort.

I wonder what else you two were born with less of.
