This one boggles my mind! I filled a plastic bag just over half full with water and sealed it. With many sharpened colored pencils I very carefully started to poke the pencils into the bag and though the other side.
Not a drop lost! One by one, I poked colored pencils in different places in the bag and in different ways.
All in all, I stuck in thirteen pencils! I did not loose hardly any water! It was so cool!
The plastic bag is a flexible polymer called low-density-polyethylene (LDPE). Its flexible properties help form a temporary seal around the smooth surface of the pencil!
That is the end of day 3! That is seven experiments down, four more to go! I am exhausted from the constant fun.
