Q: Like in the piercing shops, they pierce it with the needle and the plastic tube thingy... Then they take the needle out and leave the hollow plastic tube in the put the lip ring..,... I was wondering where can I buy that?: The needles are generally soldered by the piercer and the tube is special order. There is a reason that you have to be licensed to be a piercer you know, things like infection, sterilization, and laws

Q: Why do all squeeze tubes have a square at the top?: Do you mean at the portion furthest from the opening with the cap? Because the tube is filled from the end that is furthest from the opening with cap. Years ago (before flexible plastics existed) all tubes were made from a thick aluminum foil, the cap was put on it, the tube was filled from the opposite end from the cap, and the tube was sealed after filling by folding the open end over a few times and crimping it, which always produced a square end. Now adays with plastic tubing, which is sealed by melting the tube end together you could make it have pretty much any shape, but due to tradition a square end is still used, because that is what customers are used to buying.

Q: i connected a plastic tube about 7 or 8 inchs long onto a butane can im wondering if when i push down on the can and put a match near it can the fire go back into the can and make the can explode: Sure can, even if you've posted this in the wrong category. Funny thing about fire... it likes to burn as long as possible so if the flame makes it's way into the tube... you should duck. Don't be foolish, keep your hands, fingers, eyebrows, etc and quit playing with fire.

Q: A 0.596 kg metal cylinder is placed inside the top of a plastic tube, the lower end of which is sealed off by an adjustable plunger, and comes to rest some distance above the plunger. The plastic tube has an inner radius of 7.07 mm, and is frictionless. Neither the plunger nor the metal cylinder allow any air to flow around them. If the plunger is suddenly pushed upwards, increasing the pressure between the plunger and the metal cylinder by a factor of 2.31, what is the initial acceleration of the metal cylinder? Assume the pressure outside of the tube is 1.00 atm.Please answer in m/s^2. Thank you!: Before the sudden push, the net force on the metal cylinder is zero. This means downward force = upward force p0 A + m g = p A, where p0 is atmospheric pressure, p the pressure of the trapped air, m the mass of the metal cylinder, g the acceleration due to gravity and A the inner cross sectional area of the plastic tube. If the pressure p is momentarily increased to 2.31 p, then there is a net upward force of magnitude Fnet_up = 2.31 p A - p0 A - m g = 1.31 p0 A - 1.31 m g This net force gives rise to an acceleration that obeys Newton's second law: m a = Fnet m a = 1.31 p0 A - 1.31 m g a = 1.31 p0 A /m - 1.31 g = 1.31 * 1.01*10^5 N/m^2 * ( pi * (7.07*10^-3 m)^2 ) / 0.596 kg - 1.31 * 9.81 m/s^2 = 22.0 m/s^2

Q: You know those cheap popsicles that come in a cylindrical plastic bag? They come in big boxes inwhich they are all linked together. When I eat those, I always start coughing, and I've heard a lot of people say the same thing. What is the reason for this?: I think you can actually taste (and smell) the plastic baggy thing .....Maybe something from the plastic seeps into the popsicle?

Q: Are plastic tubes suitable for high-pressure applications?: No, plastic tubes are generally not suitable for high-pressure applications.

Q: Our side-by-side, outside water and ice collector barely lets the water come out. We have plenty of ice because it usually never used. We did notice that the plastic tubing inside the refrigerator, is wrapped many, many times in a fairly large circle, plus, there is a kink in the tubing several inches before it disappears inside of the back of the refrigerator.Should I get rid of this extra, extra tubing, along with the kink? How many feet of this tubing should be inside the fridge?Thanks to all that answer.: ours is rolled in the same position except there is no kink i just went and checked maybe thats why it dont come out good or maybe you have hard water and its clogged hope this helps you

Q: Buried PVC wire tubing (heavy) is a rigid flame retardant tube or a semi rigid flame retardant tube?: Semi hard plastic tube, Department of PVC resin and plasticizer, stabilizer and other auxiliary agent, by extrusion molding, suitable for electrical and fluid conveying pipe casing, can be used to protect the wire and cable etc. under normal temperature. The tube is provided with the length of not less than 10 meters. The colors are white, yellow, red, blue, black and ecru. The pipe connections are generally made of plastic sleeves, glued and bent freely, without heating

Q: I went to buy a plastic water bottle that has a tube inside that you frezee, and keeps the water cold they don't have anymore they sold like hot bread. I been looking everywher, and only found a place Alibaba that sells them wholesale only. A Hello kitty in OKorder which is not the one I want . If anybody knows wher I can buy i will appreciate a link or name of the place.: You can keep water cold without having to use the frozen tube. Just buy a double wall insulated bottle and that should do the trick. If you want an extra layer of insulation, you can always add on an insulation sleeve too.

Q: Are plastic tubes suitable for hot-fill applications?: No, plastic tubes are not suitable for hot-fill applications as they can deform or melt under high temperatures.
