# How do you make a Cartesian diver without a pipette?

Contents

## What causes the Cartesian diver to sink?

The reason the diver sinks when you squeeze the bottle is because the pressure exerted on the water collapses the sides of the pipette. Squeeze the bottle and watch how the sides of the pipette cave inward. This decreases the volume of the diver.

## What gas law is the Cartesian Diver?

Boyle’s Law describes the relationship between pressure and volume. Increasing pressure on a gas will decrease its volume. When the sides of the diver are pressed, the water is forced into the dropper, decreasing the volume of air in the dropper.

## What is meant by Cartesian diver?

: a small hollow glass figure placed in a vessel of water that has an elastic cover so arranged that by an increase of pressure the water can be forced into the figure producing the effects of suspension, sinking, and floating as the pressure varies.

## Would a pen cap float in water?

Like a pen,as it has a plastic body and a refill in it,its weight is more as compared to that of cap which has air pockets and its is lighter than water. 3. Thus , a pen cap floats but the pen sinks in water.

## How does a submarine sink and rise soda bottle diver Cartesian diver physics experiment?

Squeezing the container causes water to flow into the tube, which compresses the air, so the average density of the diver increases. By Archimedes’ law, once the average density is greater than the density of water, the diver sinks. This explains one way that submarines can or sink or rise.

## Why is my Cartesian diver not working?

Troubleshoot the diver if it is not working.

It should just barely float, with the air bubble (the top of the dropper, the bend in the straw, etc.) just above the water. Make sure that the bottom is sealed for homemade divers, and add a little more or less water to the eyedropper to get the right balance.
