It is known, that water is a great thirst quencher, but what can quench the thirst for knowledge?
Is the glass half empty or half full? It depends on the point of view. I wonder what thing can be placed in a full glass. How many items can be placed in a full glass so that the water will not flow out from it?
For the experiment we took a glass of 150 ml and diameter of the outlet 45 mm ( the glass could be made not from the Venetian glass), nail with a length of 20 mm and a diameter of 1.2 mm, drawing-pin, tweezers.
Mineral water Borjomi was chosen as the best material for the environment.
Carefully pour water into the glass «to the brim.» Even a little bit more!
And now using the tweezers put a nail into the glass. Put another nail. Then another … and then one by one!
My record is 121 nails! And how many nails have you put?
Oh, and finally, BONUS:
