Pokus s papírovou utěrkou

30. 3. 2010

Vezmeme si průhlednou slenici, třeba zavařovací, papírovou utěrku nastříháme na proužky a na jeden konec každého proužku uděláme barevnou fixou kolečko, vždy jen jednu barvu na jeden proužek, do sklenice dáme vodu, tak aby proužek byl ponořený ve vodě, ale barevné kolečko zůstalo venku přes sklenici, proužky se nasáknou vodou. Budete se divit co pak uvidíte.
