Movie Release:UP! : BALLOON SCIENCE FUN ACTIVITY

Have you ever wondered how many helium balloons it would take to lift different objects Up into the air?

It’s a tricky question and an even trickier answer because there are so many variables to consider. For instance:

• How big are the balloons?
• How heavy is the object?
• How quickly to do you want the object to rise Up?

We have come Up with a general formula you can use to figure out how many balloons it would take to lift… well, just about anything!

• Helium has a lifting force of about 1 gram per liter.
• An average size party balloon is approximately 30cm (one foot) in diameter.
• It can hold approximately 14 liters.
• That’s 14 grams of lift power per balloon.
• Estimate and subtract the weight of the string and the latex balloon.
• Formula: 1 balloon = 10 grams of lift power.
