[ Tsuna's just happy to contribute something to their demonstration. A mannequin will be a good way to show differences. They should probably have two to allow people to have an accurate comparison.]

I'm sure they have some mannequins they aren't using in their storage room.

[Though Tsuna is curious of how they are going to perform the demonstration.]

So how are we going to do the testing? Maybe we can stretch a pair between the both of us, and see how far it stretches before losing it's shape?
