They are used for cold drinks like smoothies, milkshakes, iced tea, and cocktails

16 fl oz of plastic translates to roughly 0.47 litres. To put this into context, it would take about one 16 fl oz plastic water bottle per pound that a person weighs to keep them afloat.

Now, 16 fl oz plastic cups are commonly used for serving a variety of cold drinks, including smoothies, milkshakes, iced tea, and cocktails. They are also used for serving boba drinks, slushies, soda, lemonade, juice, and iced coffee. These cups are often used for parties, picnics, BBQs, and everyday use at home or in the office.

The appeal of these cups lies in their convenience, durability, and ability to showcase the colours of the beverages they contain. Their crystal-like clarity enhances the presentation of drinks, making them appear more refreshing and inviting. The cups are also stackable, making them perfect for on-the-go service and storage.

Made from high-quality PET plastic, these cups are designed to be strong, reliable, and leak-proof, even when filled with ice and cold beverages. They typically come with smooth rolled rims, providing a safe and comfortable surface, and some are designed to be used with sealing machines to ensure a tight lid fit.

They are also used for floating in water, with one bottle per pound of body weight

Floating in water requires staying at the surface without sinking. This is achieved by ensuring that the weight of the water displaced is equal to or greater than the weight of the object. A 16 fl oz plastic bottle can displace 16 fl oz of water, which weighs about a pound, providing a pound of buoyant force. This means that to float a person, one 16 fl oz plastic bottle is needed for every pound of body weight.

The exact number of bottles required will depend on the thickness of the plastic used and the presence of any air gaps at the top of the bottle, as these factors influence the overall buoyancy of the bottle. Additionally, the weight of the person must be considered, as a person weighing 70 kg would require around 150 16 fl oz bottles to float.

It is important to note that the type of plastic used for the bottles can also affect their buoyancy. Different plastics have varying weights and densities, which can impact their ability to float. For example, acrylic sheet plastic, often used for brand names like Plexiglas and Perspex, has a weight of 1.19 grams per cubic centimeter. On the other hand, polycarbonate, known by brand names like Makrolon and Lexan, has a slightly higher weight of 1.2 grams per cubic centimeter.

Another factor to consider is the specific gravity of the plastic. Specific gravity measures the ratio of the density of a substance to the density of a reference substance, usually water. A lower specific gravity indicates a greater ability to float. By selecting plastics with lower specific gravities, such as polyvinyl chloride (PVC), the number of bottles needed to float may be reduced.

In conclusion, while it is possible to use 16 fl oz plastic bottles for floating in water at a rate of one bottle per pound of body weight, adjustments may be necessary based on variations in bottle type, plastic thickness, air gaps, and the weight of the individual. Additionally, the choice of plastic can impact buoyancy, with lower-density plastics requiring fewer bottles to achieve the same floating capacity.

The thickness of the plastic varies, but the air gap provides more buoyant force than the weight of the plastic

The buoyant force is the upward force created when an object interacts with a fluid, displacing it and countering the downward pull of gravity. The buoyant force is dependent on the fluid's density, the displaced volume, and the gravitational strength. When a 16 fl oz plastic bottle is placed in water, it displaces slightly more than 16 fluid ounces of water, which equates to about a pound of buoyant force. This force can be influenced by the thickness of the plastic bottle and the air gap at the top, which can vary between bottle types.

The thickness of the plastic in a 16 fl oz bottle can differ, but the impact of this variation on the buoyant force is less significant compared to the air gap at the top of the bottle. The air gap inside the bottle creates an extra displacement of air, which contributes to the overall buoyant force. This additional displacement from the air gap generally results in a greater buoyant force than the weight of the plastic itself.

The buoyant force is independent of the object's mass and is influenced by the density of the fluid it displaces. In the case of a 16 fl oz plastic bottle, the density of the plastic is relatively low, and the air gap provides extra displacement, both of which contribute to the overall buoyant force. The thickness of the plastic, although variable, typically has a lesser impact on the buoyant force compared to the air gap.

The upward buoyant force must exceed the weight of the object and any opposing forces, such as air resistance, for the object to continue rising or floating. In the case of a 16 fl oz plastic bottle, the thickness of the plastic contributes to the overall weight, but the buoyant force generated by the displacement of water and the air gap is generally greater than the weight of the plastic. This results in a net upward force, causing the bottle to float.

Overall, while the thickness of the plastic in a 16 fl oz bottle may vary, the air gap at the top of the bottle plays a more significant role in generating buoyant force. The displacement of water and the additional displacement of air due to the air gap contribute to a net upward force that exceeds the weight of the plastic, allowing the bottle to float.
