Science roadshow

Last weeks my class went to the science road show at Abundant life in the hall.My favourite part of the show was fire and ice.Why?Because a lady had a ball then got a hoop she would be able to put the ball trough,then after that the lady put the ball with the hoop in the liquid nitrogen for about 10 minutes then she got it out and put the ball through the hole and it was stuck because it had shrunking.Then we were able to do activities and if we did one with a flag you had to figure it out when you were done you had to get a teacher and explain the game to them and you would a hole in your card from the teacher,
when you have 3 holes in yours you right your name on it and school then but it in a box.Then they would call us in and they would call 2 names out one was Sam from our school and someone else from another school.After that the other lady did another part of fire and ice show.She got a candle and light it up then got something to put it out and got another type of bottle and it had oxygen in it, she squished both things together and it made a big flame.Then it was time to leave to go back to school.It was amazing.👌👍😏
