Sloths aren't dense...

... but Senile and Evil Technician definitely are. But are they more dense than water? or oil? or milk? If Evil Technician tried to drown me in honey, would I float? And does the ethanol Senile Technician adds to her tea stay at the top of the cup? So may questions that science can answer, and so little time.


And time is what you need to make a density tower. It took me a good part of a hour to carefully add the different layers of liquids so they would sit nicely on top of one another. But it looks so cool it was worth it. The liquids I've used are (from bottom to top): honey, UHT milk (stolen from the staff room), washing-up liquid, water (dyed red), vegetable oil, paraffin oil, ethanol (dyed blue).

I was about to try putting the different objects to see where they float/sink, but Evil Technician suggested we put me in! and I'm now hiding in the chemical cupboard until she gives up looking for me... 
...hang on a minute, it sounds as though the coast is clear - wish me luck.
