The audio weak,
Speaker feedback is not a problem only if the audio engineer is smart enough to employ isolation. Otherwise some feedback is inevitable.
The video you provided shows how someone can perform the water in the glass experiment incorrectly, although I have to confess I didn’t think that was actually possible. The lemon, ice and stirrer damp the vibrations that might otherwise appear and the glass should be filled to the brim since the ripples appear in the surface of the water. It’s not rocket science. At least you tried. Lol
helpful hint: the ripples that appear on the surface are a little subtle, it’s not like water is sloshing around in there although someone might be sloshed.
