Well, this is my amazing but super fragile cardboard design...!

You can see there are many colorful coca-cola straws sticking on a piece of cardboard, which is
about the size of a phone, it's easy to hold with both of your hands, I bet it is even lighter than 
your pen. I designed the patterns and lines and paths.
You'll need a little smooth ball to play this game:

The rule is to roll this ball from the START to the END by holding the design in your hands and shift in all
directions and following the path in the same time. Try not to use your fingers! You can cheat in this game, 
such as rolling the ball into a straw to get through an obstacle easily, since straws are hollow!
This is the bottom of the design:

You must notice that there are two stripes of cardboard sticking on the side, they will make holding on to
the sharp piece of cardboard to be more comfortable, you can hold your hands on it when you are playing.
I thought it would be very easy to make this design, but I was totally wrong, the most challenging part is 
to keep the plastic straws stable on the cardboard, you know plastics don't stick well... right? Some of the
straws had fell of for several times after I used some glue......

If I have the chance to recreate this design, I would like to stick the straws in an empty box, so the ball 
won't roll out and it will be more comfortable to hold on.

All right, that's how my fabulous design worked! If you, dear reader, have any suggestions or questions, just
