english: And so you see here some early studies of blocks, where those holes are actually coming through, and this is before the thermo-bimetal is applied, and this is after the bimetal is applied. Sorry, it's a little hard to see, but on the surfaces, you can see these red arrows.
non_english: Ovde možete da vidite neke  rane studije blokova, gde te rupe zapravo prolaze, a ovo je pre primene termo-bimetala i nakon primene bimetala. Žao mi je, pomalo je teško videti, ali na površinama možete videti  ove crvene strelice.
