how to make a thermometer

Sorry about the whole break but lets make a Thermometers!

Take your bottle and put (1/2 cup/1 half of a cup)of alcohol and water and pour it in the bottle.Then get your clear straw and hold it in the bottle in the alcohol and water(Which will be called Al & W.er)in the middle of the Al & W.er then get your clay and put it around the straw and the lid closing and make sure no air gets out or in,and there you go just test it by putting it in warm/hot water and it will expand.
