768 pieces of O-Pee-Chee gum was found still in its original packaging from 1979. There is one case of 16 boxes with 48 sealed packages. There has been much talk of keeping the case pristine, so too, the boxes and each package. I say no to this when valuable experiments could be done to the gum. Maybe not 768 experiments, but a few.

For those of you who don’t know, a stick of O-Pee-Chee gum was inserted inside a package with 14 hockey cards. This semi-miraculous gum would last for about a year, or at least all the way through the hockey season. But can it last a full 45 years after having been made? That is the delightful science experiment we can decide once and for all. Personally I believe that not only is it possible, it will taste as fresh as it did 45 years ago.

They are auctioning off the case. I believe science money would be well spent buying the case. Unfortunately, sport card collectors are speculating that there should be 25 to 30 Wayne Gretzky rookie cards in this case. This will likely drive up the price. Still, I believe science will be able to outbid the collectors. After all, guaranteed science out weighs what amounts to gambling on the Wayne Gretzky rookie cards. Indeed, there might be zero of these in the entire case.

This is how I fantasize the science would be done. First of all, just one stick of gum would be opened. A machine would measure the pollutants in the air released, which comes from London, Ontario’s past which was much more polluted.

Then we could rifle through the package and retrieve the O-Pee-Chee gum. Next an electronic sniffer would sniff the gum. But if I was one of the scientists, I would use my own sniffer. I imagine 45 year old O-Pee-Chee gum smells a lot like the gum did in its first year.

We wouldn’t taste the gum right away because it might be dangerous. Some of the gum may have broken down into poisons. Instead we would find out most of what it was made out of by such things as spectroscopy and using a mass spectrometer, etc.

If the gum passes these tests, it would finally be time to test the gum on a grad student. They might still die but that is the risk that senior scientists are willing to take. If they respond by going “Yuk, this is gross” then we know that O-Pee-Chee gum isn’t still good after 45 years. If they go, “Meh, let me see some reading material while I chew on this,” and then proceed to read through the opened hockey cards, then you know it has its original flavour. If they go “Yum, this is wonderful” then you know they have smoked some weed just a few minutes earlier.

Assuming the grad student went “Meh”, it is now the senior scientists’ chance to also try the gum. Does the taste take them back to their youth when they collected these cards and of course ate the gum? I suspect it will. Why? Because sugar is a great preservative and I think 45 years is nothing for something with as much sugar as O-Pee-Chee gum.

Then, if the senior scientists must, they will search through the opened cards for a Wayne Gretzky rookie card. Perhaps they can recover the cost of this experiment.

Then they will preserve the rest of the boxes and packages for 45 years in the future where they will, once again test the gum. It is after all important to find out how long O-Pee-Chee gum can last. It could be used on very long space voyages.

This Homemade Mass Spectrometer Works

Hats off to [Paul Brooking] as he shows off his homemade mass spectrometer in two recent videos you can see below. The first video demonstrates that the device works. The second video shows details about how it was made.

It's not a good starter project, requiring quite a bit of sophisticated gear including two-stage vacuum pumps, Peltier cold plates, and ion sources, but if you aren't familiar with mass spectrometers the basic idea is simple enough. You take a sample and bombard it with electrons. This creates a stream of ions of the component parts of the sample. Ions of heavy elements, obviously, weigh more than ions of lighter elements. A magnetic field deflects the ions, and the lighter ones are deflected more than the heavier ones. By detecting ions at a certain spot in the deflected beam, you can determine the relative amount of ions at a certain mass.

There are many ways you can do this, of course. But all mass spectrometers work more or less the same way with just variations on the details. In particular, [Paul's] device uses a method to detect ions called a quadrupole mass filter. There are four parallel rods that create an RF field that oscillates.

We love to see people building things that were once found only in the highest-tech labs. We would love to see more details about how to build this spectrometer so we could try to duplicate it. There is quite a bit of detail, but we feel like it would still be a big deal to recreate this yourself.

This is not the first homebrew mass spec we've seen. Some of them are quite inexpensive.
