Hi there! 
  These photos attached are Daisy.Z and Eva.Y's project. 
  Our task was to design a tool that can keep water warm.
  This is a thermos cover that keeps the water inside a muck warm. 
  We're proud of we didn't mess up everything and did a satisfied work.  
  However, the most challenging section in this experiment was to make those
foams and plastic wraps attach on the muck.
  We actually wasted a bunch of hot glue just for attaching it.
  We learned how to work as a TEAM.
  We really wanted to seal our thermos cover tighter, but there weren't
enough materials to improve it appropriately.
  As you can see, there're some black patches for decorations we did.
  Thanks for reading!
