use a rolling pin to squeez the stuff out...and there is a gadget on the market that looks like 2 fingers, you slip the bottom of the tube between the 2 fingers and just turn up so that the tube rolls around and over the fingers and the paste doesn't backflow..got he idea?..but you can always by toothpast in a pump

Use (the thick type) Unwaxed dental floss, it'll do the trick.

USE A LITTLE LESS TOOTHPASTE, BRUSH MORE SLOWLY, AND TILT YOUR HEAD BACK A LITTLE.  I TOO HATE TOOTHPASTE ALL OVER AND AM VERY CAREFUL WHEN BRUSHING.

Poppet valve would be your likely answer.\n\nCheck valve is also acceptable.

toothpaste. \nsmear a little bit on it and use your finger (go with the grain) and gently rub it. then, a moist cloth and again gently remove the excess toothpaste. i've done it a million times, and had good results.

Just keep wiggling it.  when it's just on by like one root put dental floss around the whole root and pull.  It will just slice the root and there is absolutely no pain.

It will flow in either direction if the voltage is above 0.7 volts

Place a 2 holed stopper in the top of the beaker...in one hole insert a glass "L" tube to act as spout ; in the other hole, insert a straight glass tube with a surgical tube attached to it. Blow gently into the surgical tube while puring the liguid into the funnel. At this point a funnel is not really needed for a spatterless transfer. The stirring rod is a common technique also or even this practice takes concentration.

Yes - and no - certain types of valves, such as globe and needle valves are more suitable for control than others, such as ball valves.  A ball valve will achieve 90% flow at approximately 10% open.  It doesn't give you a lot of room for control.  A globe valve, on the other hand, has a much more linear "open vs. flow" response.\n\nIf your control, however, is purely "ON/OFF" then a ball valve is perfectly suitable.\n\nOf course, in actual practive, if there is any way possible to mis-apply a valve, somebody has probably done it.

if it is yours then you need to use the program itself, and that depends on the program so i can't give you a single answer.\n\nIf you are trying to circumvent someone elses you need to use a circumventor like mine.\n\nTry acidraincloud.com

As an expert with years of experience I assure you my answer is professional:\n1. place the roll on the holder in a manner that permits the paper to hang down from the front.  Check by looking at the right side of the roll when installed to make sure the roll unwinds in a counter clockwise manner.  REASON: it is easier to control the flow of paper and easier to grasp the end of the roll.\n2. when in place on the holder, gently squeeze the roll so that the inner tube forms an oval.  REASON: if the roll is oval, it is easier to control the flow of paper compared to a perfectly round tube because the oval shape stops the paper as soon as you stop pulling.

fold a piece of paper in half and use the corner as as a toothpick to get in between your teeth.  works like a charm!

The stripes were created by a special device that was fitted to the nozzle end of the tube: a tube within the tube, if you will, about one inch in length and perforated with a ring of small holes around the top. \n\nToothpaste tubes are normally filled from the flat end, which is then folded over and sealed. In the case of Stripe, a red toothpaste was first filled around the special fitting; the white toothpaste, filled second, held the red toothpaste in place at the top of the tube. \n\nWhen the tube was squeezed, the white toothpaste would run through the special inner tube, while the pressure of the squeeze simultaneously forced the red toothpaste through the tiny orifices at the end. With the flow of red matched to the flow of white, the toothpaste emerged from the nozzle perfectly striped.
