How do you make a Cartesian diver with a pen cap?

Make a Cartesian Diver

1. Remove any labels from your bottle so that you can watch the action.
2. Fill the bottle to the very top with water.
3. Place a small pea-size piece of modeling clay at the end of the point on the pen cap. (
4. Slowly place the pen cap into the bottle, modeling clay end first.

How does the Cartesian diver experiment work?

The Cartesian diver, consisting of a plastic medicine dropper and a metal hex nut, will float or sink in the bottle of water depending on the water level in the bulb of the dropper. The more water that is inside the diver, the less buoyant it becomes and the diver sinks.

Why does my Cartesian diver not work?

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.

How do you make a Cartesian diver?

Fit two metal nuts to the bottom of the cut pipette (or add plasticine to the pen cap). Fill the bottle with water all the way to the brim. Float the cut pipette in the water and adjust the weight to allow it to float. Close the bottle and tighten the lid.

What can I use as a Cartesian diver?

The Cartesian Diver sinks or floats when gas pressure (and volume) change inside the diver. A Cartesian Diver can be made using any object that contains air, can be compressed to reduce the volume of air, and can have ballast attached. (Ballast is weight in addition to the weight of the diver itself.)

What can you use for a Cartesian diver?

Materials for Cartesian Diver

• Empty plastic 1-liter or 2-liter bottle with a lid.
• Graduated pipette.
• Hex nut (Depending on the size of your pipette)
• Scissors.
• Optional: Sharpies to decorate your bottle and dropper.
• Optional: To make a squiddy diver- electrical tape and disposable plastic glove.

Will a full bottle of water float?

Examples of Sinking and Floating Objects Similarly, an empty plastic bottle floats on water. However, when you fill it up with water, the bottle sinks. This is because it is unable to displace that much volume of water. You will also notice that it is easier for an aluminium foil to float in water.

How do you make a Cartesian diver with a paper clip and a straw?

Assembly

1. Step 1: Fold straw or tubing in half and fasten. Straws: The straws are almost 6″ long.
2. Step 2: Add weight to the diver. Pull the outside end of a paper clip out a bit.
3. Step 3: Fill the bottle with water and test the diver.
4. Step 4: Make a Hook Out of Straws, Paper Clips and Tape.

How do you make a flinker?

How-To

1. Start by filling the container with water.
2. Place a foam packing peanut in the water.
3. Place a paperclip in the water.
4. How can you combine these objects to make the peanut flink (so it doesn’t float or sink)?
5. Try attaching paperclips to your peanut and/or changing the shape of the peanut.
