    Here are our last REAL experimental results.
    1) Please look again at the link https://www.youtube.com/watch?v=xX14NK8GrDY&t=330s
    2) From 3:45 to 3:48 we have Ma = 1 kg, Mb = 4 kg and V1 = 0.1 m/s.
    3) From 3:59 to 4:01 we have Ma = 1 kg, Mb = 4 kg, V2 = 0.06 m/s and  V3 = 0.01 m/s.
    4) (1 kg) x (0.1 m/s) = ((1kg) x (0.06 m/s)) + ((4kg) x (0.01 m/s)). The last equality unambiguously shows the validity of the law of conservation of linear momentum in this particular case.
    5) (0.5) x (1 kg) x (0.1 m/s) x (0.1 m/s) > ((0.5) x (1 kg) x (0.06 m/s) x (0.06 m/s)) + ((0.5) x (4 kg) x (0.01 m/s) x (0.01 m/s)). The last inequality unambiguously shows the invalidity of the law of conservation of mechanical energy in this particular case.
    6) How to reduce friction inside the zigzag channels? The answer is simple — by using permanent magnet slides. (There are literally hundreds of permanent magnet slide designs in YouTube and in Google.) Please look at the links below for example:



    7) The permanent magnet slide design:
    a) reduces friction (and the related generated heat) practically to zero;
    b) reduces the experimental error (due to friction and to the related generated heat) practically to zero.
    8) And if the above mentioned experimental error is practically equal to zero, then this experimental error can be neglected (as it is much smaller than 1 %).
    9) Alternatively you can use electrostatic levitation, rolling friction instead of sliding friction, etc. Besides modern tribology (this is the science, which focuses on sliding/friction phenomena) suggests a great variety of high-tech materials and/or lubricants’ which are also able to reduce sliding friction (and the related generated heat) practically to zero.
    10) In one word, you can carry out easily the above mentioned experiments in your garage or in any standard school laboratory (or by using any other simple DIY (DoItYourself) methods).
    Looking forward to your comments.
