It is not safe to use balloons to lift a baby or any person. Balloons are not a reliable or stable means of lift and can easily pop or drift away, posing a serious risk to the safety of the person being lifted. Additionally, using balloons as a lift would not provide any means of control or stability, which could lead to serious accidents or injuries. It is important to use proper lifting techniques and equipment when lifting a baby or any person to ensure their safety. If you need to lift a baby, it is recommended to use your arms and legs to lift and support their weight, rather than relying on any other object or device, but for the sake of an experiment, lets calculate this.

The amount of weight that a helium balloon can lift will depend on various factors such as the size of the balloon, the amount of helium gas inside the balloon, the material of the balloon, and the atmospheric conditions.

In general, a helium balloon will not be able to lift more than a few ounces of weight, even under the best conditions. The lifting power of a helium balloon is limited by the buoyancy of the helium gas inside the balloon, which is determined by the density of the gas and the volume of the balloon. As the weight of an object increases, the amount of buoyant force required to lift it also increases. Eventually, the buoyant force of the helium gas will not be sufficient to lift the object, and the balloon will begin to descend.

The amount of force that a balloon can exert depends on a variety of factors, including the size and shape of the balloon, the material it is made of, the amount of helium gas inside the balloon, and the ambient temperature and pressure.

Helium is less dense than air.

Yes, You are correct that helium is less dense than air, which is why it is used to fill balloons to make them float. The force exerted by the weight of the helium in a one cubic foot balloon would be approximately 0.0114 pounds, as you calculated. The upward force exerted by the air would be equal to the weight of the volume of air that the balloon displaces, which would be approximately 0.0807 pounds for a one cubic foot balloon at sea level and standard temperature and pressure. However, it is important to note that this upward force is not a direct force on the balloon itself, but rather the buoyant force that acts on the balloon due to the difference in density between the helium inside the balloon and the air outside the balloon. The buoyant force allows the balloon to float, but it is not capable of exerting a significant amount of force on objects.

How much does a single helium balloon lift?

A single helium balloon can lift up to 0.0807 pounds or 0.4 Kilograms. This means that to lift 10KG or 22 Pounds you will need 26 Single Helium balloons.
