first day of think up

Today was the first day of think up.We first play 2 truth 1 lie.Then, we brainstorm is a sheet of paper. I thought of a robotic arm that cleans your table and I also thought of a shirt that changes sizes while you are growing. But the problem is the shirt will run out of ingredients you need .the only way is use stronger cotton and stretch the shirt.But I am sticking with my robotic arm.I learnt how to use lego to make a modal of the robotic arm.Today the challenges I have faced is playing power-ball.I have faced using different kinds of lego to make my prototype too.
