When you release the bottle, the pressure lessens and the water moves back out of the straw. As the air bubble gets smaller, the density of the diver increases and the diver begins to sink. When you squeeze the bottle, you increase the pressure of the water in the bottle, so water is forced up into the straw compressing the air bubble in the straw. A small bubble of air gets trapped in the straw when you put the diver in the bottle. When you first put the diver into the bottle, the combined density of the diver, straw, paperclip and playdough is slightly less than the density of water, so it floats. Objects will sink in water if their density is greater than 1 g/mL. Objects will float in water if their density is less than 1 g/mL. This experiment is also referred to as the Cartesian Diver Experiment and it is a simple and fun way to teach kids about density and how it impacts whether an object will sink or float.ĭensity is a measure of the mass per unit volume of a substance. Video Tutorialīottle Scuba Diver Science Experiment Step by Step Instructional Video How Does the Science Experiment Work Write down your hypothesis (prediction) and try it out and observe what happens.ĭo you know why then you squeeze the bottle the diver sinks to the bottom and when you stop squeezing the diver floats back to the top.įind out the answer in the how does this experiment work section below. Step 6 – What do you think will happen when you squeeze the bottle? What about when you stop squeezing the bottle. Carefully place the diver into the bottle and screw on the lid. Make sure to fill it to the top, otherwise, the experiment won’t work. Step 5 – Fill the two-liter bottle with water. If it doesn’t float, your straw may have a hole in it. Step 4 – Fill a glass with water and put the diver in. Then place a small piece of play-dough or putty on the diver’s feet. The diver should look like he’s wearing a scuba tank. Step 3 – Slowly slide the straw onto the diver as shown above. Each end should be secured by the ends of the paper clip. Step 2 – Cut the straw and position it on the paper-clip as shown above. Helpful Tip: Download the Template for the Bottle Diver Here The diver should be approximated an inch and a half tall. ![]() I lightly sketched my diver on my foil before I cut him out. Step 1 – Cut out your diver using the same shape and size indicated above.
