II:
Step
6 What is the minimum amount of weight that
has to be attached to point 1 in order to make it
be the bottom of the balloon? Record this.
Step
7 How much weight can be attached to point
2 (with the minimum weight of Step 6 still on point
1) without the balloon sinking to the floor? Record.
Step
8 Take your answer from Step 7 and divide it
be the number from Step 1. Then multiply this number
by 100. This number is the percent of total weight
the balloon can carry when point 2 is the top of
the balloon. Why are the numbers from Step 5 and
Step 8 different?
Step
9 What is your weight? You probably know your
weight in pounds, but all our earlier measurements
were in grams, so we need to convert your weight
to grams. To do that, multiply your weight by 453.6.
Now divide your weight in grams by the number from
Step 1. This is the amount of balloons it would
take to lift you into the air!
Step
10 In my experiment, TopHat, there is one big
helium balloon. To give ourselves an idea of how
big that balloon is, let's see how many of our little
balloons it takes to be equal to one big balloon.
The total weight of TopHat, in pounds, is 8300.
Again, we need to convert this number to grams by
multiplying by the number 453.6. Now, divide the
weight of TopHat in grams by the answer from Step
1. Wow, that's a lot of balloons!
