Tinman,

That is an optical property of thin films.  Think soap bubbles and oil films on water...

This explanation dose not fit the picture supplied. The photographs i supplied from the apollo mission show clear and decisive edges of each different color on each piece of tape. The examples you supplied by way of the link you posted show merging colors with undefined blurring transitions.
Below -the first picture shows the effect you are talking of,and the second picture shows the defined color differences between each piece of tape.

Nice this guy did the timing for each event comparing known earth (3 seconds for 10 drops), feather hammer(11 seconds for 10 drops) and the accidental rock drop (4 seconds for 10 drops)   https://www.youtube.com/watch?v=46dW5rzhtMI

MH-you have finally flipped your lid.
Equal and opposite forces MH. You cannot get more out than you put in.
Fact-less energy is required to lift the same mass to the same height than is required here on earth.
Fact-less energy is returned upon impact on the moon,than it is here on earth.
Fact-the reason for this is,although the mass remains the same,the weight dose not
Fact- The mass equivalent in KG's on the moon is 21.45
!NASA! fact--the hammer and feather fall at the same speed,but the hammer will impact the ground with more energy-Why?--the feather is lighter.
Fact-dropped from the same height,the hammer will impact the ground with more force than it will dropped from the same height on the moon.

You have completely lost the plot if you think that the weight changes nothing,regardless of what the mass is. Not only that,but your earth quake theory is utter rubbish-provable beyond any doubt here on earth where greater impacts are made--due to the greater weight

After i have put PW's theory in the bin,i suspect you will return to your earth quake theory

Let me translate this for you Brad into something more coherent.

You are basically stating that the final velocity will be less because you are on the moon.   I already told you that I don't care about the final velocity.

A quote from you, "The mass equivalent in KG's on the moon is 21.45."

Let me translate that for you, "The weight equivalent in KG's on the moon is 21.45."

Can you understand how you have an issue?

The earth quake theory is not "utter rubbish."   If you drop a mass of one kilogram onto the surface of the moon from a height of one meter, where does that energy go?

I watched the video.  I believe the flag moved due to being hit by the exhaust from the spacesuit sublimator.

In the video, if you can stand listening to the sound track, you will hear NASA say "coming up on water".  The astronauts are being told there EVA must come to an end because the portable life support system (PLSS) is running out of water.

The PLSS used a rebreather and CO2 scrubber.  Oxygen, as a consumable, was rarely the limiting factor regarding EVA time.  However, the suits used a "sublimator" for cooling which consumed water and it was that water which was typically the EVA limiting consumable.

Somewhat simplified, the sublimator forces water thru very tiny pores on the inside of a cylindrical metal plate.  The water freezes.  Warm water from the suits garment layer needing to be cooled is run thru tubes in contact with the plate.  This "melts" and "boils off" (actually, "sublimates") the water (which does so at a lower temp in a vacuum).  A fan is used to purge (blow out) the water vapor from the inside of the cylindrical sublimator.

If I recall correctly, the exhaust for the sublimator is thru a relatively large circular opening in the left side of the PLSS hard shell.

Here are the two reasons it can not be the ejected water from the sublimator unit.

First-in the video,we see the astronaut bouncing past the flag. We clearly see the flag waver as he just passes the flag. If it was the ejected water(now turned into extremely small ice particles due to the rapid expansion of the water mist entering an extreme vacuum hitting the flag,then the flags first motion would be away from the astronaut. As can be clearly seen in the video,the first motion of the flag is toward the astronaut. This reaction is exactly as it would be here on earth.

Second- The pump and fan you speak of is between the middle and left side of the back pack unit. The sublimator units cooling plates run across the top of the PLSS unit. The waste vent is on the right hand side of the unit. On the left side of the PLSS unit,there was provision for an extra bag/luggage storage sack. The first two pictures below show the left side of the PLSS pack,and as can be seen in the first picture,there is no waste vent on the left side. The second picture show the extra luggage sack fitted that would cover any vent. The third picture shows the vent on the right side of the PLSS unit. So this also means that it was no ejected water from the pack that makes the flag waver,as it is on the wrong side.

Brad:

Here is a little bonus round that will throw a monkey wrench into the experiment that was locked up inside your head this whole time.

Suppose you are on the Earth and you do a straight jump up from a standing position.  Let's say you put a moderate amount of effort into it and you jump up six inches and then land.

Now, just imagine everything stays the same but the gravity is decreased to the moon's gravity.  This is just a thought experiment.

You jump up with the same amount of effort.  Naturally you will jump up much higher and you have more air time.

So what about the landings in both cases?

The answer is that in both cases you will land with the same speed and therefore you will experience the same force and the energy will be the same.

Now, going back to the moon, we see an astronaut jumping past the flag.  He is hitting the ground with the same amount of force if you imagine him doing the same thing on Earth.

In both cases, the landing back down to the ground is just as hard as the amount of effort you put into making the jump up in the first place.  Except on the moon you have more air time.

The moral of the story is that the jumping astronaut will hit the moon just as hard as if he was jumping on the Earth.
