Density is a fascinating scientific concept, but it can be tricky to grasp if you’re just reading a textbook definition. Bringing density to life with a hands-on experiment makes all the difference. That’s exactly what science YouTuber DaveHax demonstrates in his fun video “Denser Than You Think – Science Experiment”.

In the video, Dave starts with an empty glass and adds some syrup. He then tops it off with water, creating a thicker layer of the syrup-water mixture. Finally, he pours oil over the water, filling the glass. After giving the liquids a few minutes to settle into layers, the results are magical.

The syrup, having the highest density, sinks to the bottom. The oil, with the lowest density, floats on top. Dave then drops various objects into the glass to further showcase density in action. A metal nut sinks rapidly through the layers, coming to rest on the dense syrup. Next, a grape sinks through the oil and water but bobs in the syrup, less dense than the nut but more than the liquids. A plastic bottle cap also sinks through the oil, eventually settling on the water. Finally, a piece of sponge perches atop the oil, the least dense of all.

This simple but fascinating density experiment can easily be recreated at home with basic kitchen ingredients. It’s the perfect hands-on way for kids and students to see density in action. The aha moment when the liquids separate into brilliant bands of color is undeniably cool. Experiments like this bring scientific concepts to life. So next time you need to liven up a science lesson, give density a whirl.
