Density Tower

Hi. In this Instructable I will show you how to make a cool science experiment at home. This experiment will help you understand the physical properties of liquids.

For this experiment you'll need a tall, straight-sided glass and a number of ingredients. You don't need all of them, but the more the better! Measure out equal quantities of: Ketchup, honey, syrup, milk, dish soap, vegetable oil, and rubbing alcohol. Work out the volume of the glass, divide that by the number of times you have and that will tell you how much of each liquid you need.

Pour the first item that you have got from the above list (in that order) into the glass. It is very important that it doesn't touch the sides.

Following the order of the list, pour in each of the liquids one by one as slowly as possible, trying not to get any down the sides. It doesn't matter if the liquids are a little mixed up at this stage.

If the liquids have merged a little, then give the mixture a few minutes to separate. You are done!
