Dakota did not get to try a hot water bottle on her first visit to the Lab, which was probably just as well, seeing as how extremely nervous she is around any inflating rubbery object. This time, she is able to place the object under test outdoors, while blowing from the comfort of the lab, with glass between her and the explosion. Sage, on the other hand, is less afraid of the explosion, but less sure she can produce enough pressure to cause one. So the two work together to make this one happen.
