You are trying to make balloon sculptures. you twist the balloons gently, but they keep popping. besides trimming your nails, how could you you prevent that? why will your strategy work?

Maybe use gloves that are easy on the finger tips or very flexible, like a strong latex, or a couple of layers of regular latex gloves. Maybe use rubber finger covers meant for string instruments, as they are rubber and will help you grip the balloon and wont pop it. Or maybe try deflating them a bit because as you twist, you're forcing more air into different parts of the balloon which causes too much pressure. It will look the same if you just deflate it a tad.

Hope this helps!

The independent variable is the type of music.the dependent variable is the pulse rate.the intervening variable is the age of the subject.if the mother does not like rock, her pulse is likely to not increase.the same might be true for the sister.the friend may like rap and gets excited.to establish cause/effect relationship, all of the subjects must be consistent.hope i .
