Upcoming TEST TUBE TORCHER TESTS

The word "Torcher"  was an accidental discovery.   I had been trying to come up with a catchy name for these demonstrations.   A viewer had misspelled  "torture"  in the comments and bang!  that was it.   "Torture by a Torch"    

I have to admit that the inspiration behind these tests were  "RHNB"  (red hot nickel ball)  where a guy heats up a metal ball with a homemade oxy/hydrogen torch and sets the ball on various objects.   It seems silly but it is fascinating.  I wanted to come up with something the viewers of those video enjoy but not copy his basic idea.  There are too many people on Youtube who have no problem copying the ideas of others.  The TTTT's  compliment RHNB.  Everyone wins.  
I have always enjoyed  "potential energy"  and the TTTT are a good demonstration of that,   along with thermodynamics.   Just like compressing a spring,   applying  heat energy to a liquid inside a sealed test tube is storing a LOT of energy.    Water expands 1600 times when it transitions from a liquid to a vapor.   One would think something like gasoline would be more energetic than water but it only has an expansion ration of 160:1  (1/10th of water!)

My tests are simple,  cheap and easy to film.   I am able to use suggestions that viewers post and that makes it fun.   Not everything is possible though.   For example,   I don't have nitroglycerin and I am not going to put stuff in there that is too weird and creepy.   I'm trying to use simple,  household materials and avoiding compound tests where I put two or more different materials in a test tube.  (at this time)    Also,  the substance has to melt to a liquid 
AND have a boiling point below the melting point of glass in order for these to work,    so using wood or metal  (gallium) isn't going to built up any pressure.  
Sometimes a viewer will suggest something SO cool I skip ahead and will do that test first.


Even though I have posted numerous TTTT videos,   I'm still in the test-phase to see if there is long-term interest in these.   The response from viewers has been good.   A few viewers have said they were boring,   but you can't please everyone.    There's no shortage of bitter people on YT who seem to think only their opinions matter.   

Upcoming videos: (in no particular order)
Cascade      Tapatio hot sauce       DOT3 brake fluid      10% Nitromethane model fuel 
Chocolate Chips        ammonia       mustard      Frog Lube     Cornstarch/Water 
Crayons   Gasoline   Alcohol

Test Tube Shotgun Ammo?

 
Yes,   I still plan to post crazy shotgun videos,   and other shooting videos.
Unfortunately,  I go through dry-spells with the shooting stuff because of weather,   work,   trying sync schedules with friends,    and finding places to film.  
 
Just to keep you abreast at what is going on,   here are some Pyrex test tubes that have lead shot in the tip and the rest if filled up with solid crayon wax.   I used orange/yellows hoping this color will show up well with the HS cameras.     Each projectile weighs 1oz.  or less.    I used  RIO  high brass 12ga shells.   They are blue.   But I am pretty impressed with RIO even though it isn't a really well-known brand.    I actually like these better than Federal shells.    Really good stuff but usually these are a couple bucks more per box.  The boxes are ugly as hell,   a mud-brown color.   They need to fire their marketing person and redesign their packaging to focus on the cool blue color their shells are.

The  "Phillips 22"  round?   What the heck is that?    I like to tinker around with .22 bullets.   What I did with these rounds is create a segmented hollow point using just a phillips screwdriver.   We will be doing to some tests and hopefully include another channel to do some ballistic gel testing.     

Just waiting for some good weather to film in.    California has been going through a dry year with little rain.   The reduced rainfall and snowpack is bad enough,  but  the air quality has been really bad.   I live in the middle of California and it is like a big bowl,   the air quality is often very bad.   Rain cleans the air and we can see the mountains that are normally hazy.

How much pressure?

Temperature and pressure is relative inside a confined space like a boiler,   or in our case,  a sealed test tube.   

I,  as well as many other viewers have wanted to know how MUCH pressure is building up inside these test tubes.    I don't have any small pressure gauges,  especially a high-pressure one with a range that goes up to 1000 psi.  

I do have a remote thermometer and I am going to do a video where I epoxied the probe inside the test tube so we can see what the temperature is.

Test Tube Torture Tests

For the next TTTT,   I am going to put microwave popcorn in a test tube.   Have you ever cut open a bag of microwave popcorn?   It is nasty looking.   It looks like something a cat threw up.  

The test tube will be sealed up with an epoxy plug which will cause the internal pressure to increase as the heat increases.     Popcorn pops because of the moisture inside the kernel.  The shell of the kernel allows the pressure to build up inside.   Eventually,  the kernel can no longer hold the pressure and the pressure is instantly released.  The moisture expands about 1600 times.   The starches inside behaves like foam and expands and solidifies almost instantly.

Inside the test tube,   the pressure inside the kernel will be about the same as the pressure outside the kernel.    The popcorn will not pop.   But,  once the epoxy plug blows and the pressure drops to atmospheric pressure.... the kernels will instantly pop.
