Could you help me here? I've answered a physics question which asks about how to measure the volume of an inflated balloon. I would like to make it more natural because I feel there are too many colloquial expressions as well as quite a lot wrong word choices and grammar mistake. Could you help me please? Please feel free to adjust any words (Is the word adjust correctly used here?) Choose a cylinder that should be large enough to keep the balloon inside; Pour some water in and record the initial volume V1; Insert the inflated balloon and record the new volume as V2. The volume of the inflated balloon can be calculated from V2 minus V1.
