We eight kids like to potter around productively...Mama wants to remember these delightful days when we have all grown up and left home, so we are creating a record for her.

By J12 and J11 (self-editted without any Mother-Help)

In the pouring rain we dashed across MOTAT to the Robot Exhibition. There were some remote controlled robots, which we were allowed to have some fun with. J11's favourite was a dinosaur that could run quite quickly and move its tail and head. K9 directed one of the dinosaurs *almost* under one of the cars that was parked there. There was a robot robot (do you know what we mean by that? it looked like what you expect a robot to look like) - it could bend down, roll over and say Hello, as well as move anywhere you sent it.

Do you have any idea what this is?
It looks like a piece of cardboard with straws and string, doesn't it?
What you can't see are the rubber bands attached to the back.

They work all together as a robotic hand.
When you pull a certain string, it will move a finger, stretching out the rubber band (just like a tendon). Of course, when you let go of the string the rubber band pulls the finger back straight again.

When we got home Grandpa used this to explain to us about his Carpal Tunnel surgery.
It was also easy to see why the end of Mama's finger hung lifelessly when she snapped one of her tendons.

Very Interesting.
