Day 4-
So today we started by making a new cardstock house to replace our lost cardboard house. We wanted to make it rather large, seeing how cardstock weighs less than cardboard. So here are our new cardstock house dimensions-
Height- 0.3683 m
Depth- 0.2794 m
Width- 0.4318 m
Weight- 207 grams
So the new cardstock house weighs 37 grams more than the cardboard house we lost. It took thirty balloons to lift the cardboard house at 170 grams, so after some math and rough calculations we figured it would take around 35 balloons to life our new house. (Here is how the math went down- so for every 170 grams it takes 30 balloons, so 170 divided by 30 and rounded is 6. So each balloon takes off 6 grams. Now 207 divided by 6 rounded equals 35.)
This was based though on the balloons we used Monday, not the ones we used today, also my math could be wrong which could also explain why when we recalculated we saw it would take around 60 balloons. With thirty balloons tied to the house the weight went from 207 grams to 120 grams. So in this case for every 30 baloons the house weight went down by 87 grams. So lets say we add another thirty balloons, the weight would then go down to 33. Now divide 87 by 30, and rounded you will see that one balloon takes off three grams. So we would need around 11 more balloons for those 33 grams. So after all of this confusing math, it would take around 71 balloons to lift the house. But the math could be wrong, and depending on how big we filled up the balloons we just decided to say it would take around 60 balloons (cause we could fill the balloons up with more helium than we had been.)
Wow, okay so now that you are probably all confused or just skipped that whole math part, I can say that we did not get the house to lift today. We got up to 35 balloons and ran out of helium. The 35 balloons did make a difference on the weight, but not nearly enough, so now we will try again on Monday
