How to Use Coin Tubes
Before I begin, I am not encouraging the use of PVC based products to store your coins. If you are going to use a PVC based product, ensure that it’s for the shortest amount of time possible.
With that said, plastic coin tubes are an alternate way for you to store your coins. It’s simple enough to describe. The tubes are plastic and you get the size that will fit the coins that you want to store. They come in different sizes.
These tubes are easy to use. All there is to it is that you load each coin into the tube until it’s full. This is not the way to go if you are the kind of person who wants to keep looking at your coins, because you have to keep taking them out of the tube. Remember that when you continuously handle your coins with your bare hands, you are aiding their degradation. So, this is a good mode of storage for those people who just want to store their coins. Coin tubes will help you save a lot of storage space because the coins are bundled in a compact space, as compared to when you put them in a display case or a coin album.
Another advantage of these tubes is that when you pack your coins in them, they are so compact that there is absolutely no room for movement. This means your coins will not rub against each other, thus preventing the risk of scratches and abrasions.

Why was JJ Thomson unable to determine the charge of the electron using the cathode ray tube experiment?
He was only able to determine that the charge is negative, not the actual value of 1.67 x 10^-19, why not?
The experiment measures how much a charge deflects in a field. The more charged a particle is, the more it will deflect (F=qE or F=qv x B). But at the same time, the more massive a particle is, the less it will deflect (a=F/m). So a very light particle with a small charge will deflect by the same amount as a very heavy particle with a lot of mass. By looking at deflection, all you can determine is the charge to mass ratio, not the charge itself (unless you know the mass of an electron, which Thomson did not know). It took Millikan's oil drop to determine the charge, because in his experiment he measured the charge of an electron relative to the mass of an oil drop, which was already known.
