The living force is all around us. Just kidding. Forces are all around us. In modern days people measure weight (mass) by pounds of kilograms, but here is some simple intructions on how to make some simple scales:

Get a large yogurt pot and tie four pieces of string evenly around the edge. Tie the ends of the strings together. Get a slightly longer piece and tie that to the knot you made. ATTACH the end of THAT string to a bent wire coat hangar (shape it so it has a hook on both ends and a kinds of pointer pointing outwards). Hook a rubber band onto the other end of the coat hanger and attach the other end of that onto a paper clip. *DEEP BREATH* hang it from a hook. It SHOULD look like this:

Gosh, are you still with me? Put a piece of paper behind it and start measuring wieght. Write them on the paper.

WHAT THE HECK'S GOIN' ON?

Well, remember Sir Isaac Newton? You know, the guy who had the apple fall on his head? He discovered gravity. These scales would not work without gravity. If gravity was not pulling everything back to Earth, they would just float around and not do much at all. Newton made up his own wieght measurment. 100g = 1N (Newton) and 1 kg (kilogram) = 10N. Simple.

I saw this on Bang Goes the Theory program, and it is REALLY STICKY! This is how to make it: Pour a cupful of milk into a saucepan and heat it up on the hob. Take it off when it starts to boil. Add a tablespoon of vinegar and stir the mixture. It will break up into curds. Strain the mixture over a jar, use a spoon to push it through if needed. Remove the curds from the strainer and place back into the saucepan on the hob. Add 100 ml (1/2 cup) of water and a tablespoon of bicarbonate of soda. When it starts to bubble remove and use the mixture as the glue. (NOTE!! Please leave the glue (when applied) for 24 hours for it to dry). WHAT THE HECK'S GOIN' ON? By adding the vinegar to the milk, you have change the composition of the liquid, and by leaving it to set, it turns into a solid, holding two objects together.
