тығамыз да, қалыңдығы 0,5 см болатындай етіп жақсылап жуылған өзен құмынан қабат жасап себеміз.

      Түтікшелерге 0,1 н КОН ерітіндісінен 15-20 мл құямыз, бірақ оның жоғарғы деңгейі түтікшенің шетіне бірнеше см-дей жетпей тұруы керек. Екі түтікшеге платина немесе мыс электродтарын қойып, оларды жоғары вольтты түзеткіштің клеммасымен жалғастырып, тоқты қосамыз. 120 В кернеудегі ток күші шамамен 50-250 А болады.

      Тәжірибенің нәтижесі: Ток қосқаннан кейін бірнеше минут өткен соң, катод жазықтығындағы ерітінді шамамен 1 см-ге көтеріледі, ал анодта 1 см-ге түседі. Екі жақтағы деңгейлердің айырмашылығы 2 см болады. Сонымен бірге оң элоктродты түтіктің құм қабатының ішіне саз болшектері өтіп, лайлы жүзгін байқалады. Теріс электродты түтікшеден ерітінді мөлдір болып табылады.
