To determine how many helium balloons to lift a person: Determine your weight - for instance, 75 kg. This number should include everything that will be flying, so your clothing as well. Every gram counts! Choose the size of the balloons. Let's assume we are using regular balloons from an amusement park with a diameter of 30 centimeters …

Add the weight of the three empty balloons and their ribbons to get the buoyancy. For example, say the weight of the spoon is 20 g, the weight of the spoon with the balloons and ribbons attached is 15 g, and the weight of the balloons and ribbons is 3 g. Then the total lift supplied by the helium gas equals 20 - 15 + 3 = 8 g.

F B = w fl, where F B is the buoyant force and w fl is the weight of the fluid displaced by the object. This principle is named after the Greek mathematician and inventor Archimedes (ca. 287–212 BCE), who stated this principle long before concepts of force were well established. Figure 14.21 (a) An object submerged in a fluid experiences a ...

Use a ruler to measure how much of the BT is above the water line. Remove the boiling tube from the water. Dissolve lots of salt in the water. Put the boiling tube back in the water and measure how much now is now above the water line. The boiling tube should float higher in the more dense (salty) water because the upthrust acting on it is greater.
