Great video! ... For a moment I thought that the grains+silo weighted less than the grains alone... Then I did the mental free body diagram and concluded that it was impossible... Finally I looked carefully to the setup of the experiment and the silo walls were being held, so the purpose of the experiment is to show that the grains alone weight less because they hold onto the walls of the silo by friction xD... Thank you for sharing all this great experiments, visualizations and insights!

I did a rewind for the same reason. Would be a little better if she pointed that out.

Oh thank God, Great observation! I was thinking all my years as an engineer are useless because I can't understand this simple situation :D

is there a supplier of those plastic disks for the average person? that stress pattern is beautiful.

Smooth-On is what we typically use. ClearFlex for polyurethane disks. (Trial size is ~$50.) You'll need to cast in a mold, which smooth-on can also help with. Then you need some polarizers -- cross two pairs of sunglasses around the material you made and then shine some light through! (Preferably you want circular polarizers but that won't be cheap)

At 5:30, you can reproduce something similar by weighing yourself with the scale resting on carpet which I do all the time just to make myself feel a little better about myself. You will always weigh less if the scale is on a carpet or other shock absorbing surface. So I guess we can say that the steel balls were acting as a long tall shock absorber. Someone should patent that.

I find the experiment at 5:30 to be a bit misleading albeit amazing, (unless you know what's going on with the retort-stand behind the silo) and most non-experts watching this video would think that the silo weighs less than the bowl (which is not true, but also not the message you wanted to convey..)

Seems to be a lot of this channel, unintuitive things explained poorly and only make sense if you already have an understanding of some underlying phenomena

It just seems like she weigh the grains while slowing down the rate of filling.

If sand's granular matter, wouldn't that make it a granular solid aswell?

The force transferred to the walls has nothing to do with it. Even the friction must be countered at the scale. Only factor that can affect the rate of weight increase is the rate of input flow. This is very misleading.

The transparent tube (silo) is fixed to the table. The scale is not in contact with it
