So then they are banging these boards on the corner of the stage and nothing is happening. So I just went the full "Oh noes! Whats wrong? You could break dem before but not now WTF?!"

After about 2 minutes of this (Sensei was doing weapon kata demonstrations during all this) I explained the physics to the kids and showed them the grain of the board and amazingly they were able to break them... I'm not sure if it was because I showed them about breaking with the grain or if their chi energy had recharged after breaking the boards earlier?... It was probably the latter
