There were some awesome things I saw in the closing performance. In the last performance they showed some devices. It was x-rays,and heat device that was like a thermometer. They pushed it down the test dummy's throat and it showed the inside of him. Another man came and asked for a volunteer, Ana put one glove one her hand then she placed both of her hands on a wooden board. It showed the heat of her hand. Sadly we had to go but it was fun.
