What is the fastest way to melt rubber inside a steel tube?

something really harsh like paint stripper would have an effect as its quie volatile. if you can pour a flammable liquid into the tube such as petrol etc this will light from a distance but be super careful

Contain it in a tube.

Fill a long tube with solids and try to blow air through it.\nPut a flabby piece of rubber at the end.\nYou will get all your answers then.

Rubber in contact with other surfaces can yield friction coefficients from 1.0 to 2.0.\n\nhttp://en.wikipedia.org/wiki/Friction

gorilla glue! \nor possibly rubber cemente

Look into a product called Alumaloy. It's like welding that you can do with an ordinary propane torch. They claim its stronger than steel and will bond to any kind of metal.

For Fastest Speed, Hot water\nFor safer method, cold water

Toss it in the microwave for 30 seconds.  The end will peel up a bit.

That depends on the alloy of steel you are talking about. Most steel has other metals added to tune its properties, like strength, corrosion resistance, or ease of fabrication. Steel is just the element iron that has been processed to control the amount of  carbon. Iron, out of the ground, melts at around 1510 degrees C (2750°F). Steel often melts at around 1370 degrees C (2500°F).

If you are doing it in a laboratory setting, you can mix it with carbon and reduce it to the metal. You will need high temperatures, though.

Do you have a dremel tool. If not use a metel file and make an indent around the entire tube.Put a little spit on your finger tip and rub it on the indent. Take a tourch and heat the tube at the indent until you can see it start to turn red and snap the tube.

Place a single layer of one piece of material at a time over the top of an empty beaker and secure it using a rubber band. The material should not be pulled too tightly. Start pouring water from the other beaker into the first through the layer of material as quickly as possibly but without spilling any water. Use the stopwatch to see how long it takes to transfer equal amounts of water. Relative permeability will be inversely proportional to the times. Water will not permeate latex rubber, if you try pouring it it will simply pool, giving infinite time and zero permeability. Pouring through the clothes the water will pool a little but still pass through, giving shorter times and higher permeabilities.

yes, with an alloy or equal or lower melting point

You could try to make an accurate experimental thermometer by glueing two strips of dissimilar metals together along their lengths. Perhaps try copper and steel or copper and aluminum or steel and aluminum.  Try perhaps one half inch wide by six inch long strips.  Use sheets of metal that are equally thin.  Perhaps cut the strips from aluminum soda cans and steel soup cans, etc.  Use a magnet to check for steel vs aluminum.  Glue the strips together using epoxy or super glue.  Attach one end of the combined strip to a firm base and leave one end free to move in front of a paper scale.  You now have a bimetalic thermometer.  The thermometer can be made to be more sensitive by using greater length strips and bending the strips into a spiral and attaching a pointer to the free end of the spiral to amplify movement.  This is how most oven thermometers are built except the metals are joined without glue.  The principal of operation of a bimetalic thermometer is that one  metal expands or contracts more or less than another metal.  When joined, a temperature change causes the combined strip to bend.  You can calibrate your thermometer by marking its "pointer" position at two or more large temperature changes then calculating the total deflection divided by the total temperature difference to get deflection per degree (either F or C).  Be careful with tin snips and epoxy or super glue.  Good luck.\n\nAs an alternative, you can make a highly accurate experimental thermometer by winding very thin insulated copper wire (like that used in toy motors) around a wooden spool and connecting the scraped   wire ends to an accurate ohmmeter to measure resistance change vs temperature change.  Calibrate as before but remember that calibration temperatures must be steady long enough for any lag to catch up.  This is called a resitance thermometer and accuracy will depend on the length and thinness of wire and sensitivity of your ohmmeter.  Also the ohmmeter should not cause enough current to flow in the wire to heat the wire.  Observe for drift (increase in resistance and temperature) while taking measurements.
