"Chance Encounters"

Kelsey's description: Our game was called The Magic Tube. There were three holes in the base. You had to take one of the red balls and drop it down the tube in the top of the box, but before you did that you had to guess which hole the ball would come out. If you guessed correctly you would win a point.

The game turned out to be a great success, although we had trouble making the game. Each time the little kids came we would have to put the game on the ground because they couldn't reach the tube. I think the little kids enjoyed it and sometimes they wuld just drop the ball down the tube without even guessing, which was frustrating.

The theoretical probability of scoring in our game was 33%, 1 out of 3, but it ended up being 41%, which we didn't expect it to be.

Next time we do this game I wouldn't change the design but I would try to think of another way of making the ball come equally out of all three holes.

I really enjoyed working with my partner and I think we made a successful game.

Nicky's description: Our game was made of a box, cardboard strips, wood strips, a toilet roll, clay and a huge round piece of wood. When we had finished the whole thing, to me it looked like a normal decorated box with a coloured toilet roll sticking out of the top.

The rules are that you had to take a red ball and then guess which of the three holes it would come out of. If if comes out of the hole you chose you win, but if it doesn't you lose.

In the fair I think it went quite good and we didn't have any trouble except for two things. Those two things were sometimes when someone dropped the ball in the tube the ball got stuck on the clay, but that wasn't really much trouble. The thing that annoyed me was that we had to tell the little kids how to play the game hundreds of times because they didn't understand or they couldn't reach the tube at the top so we had to pick the game up and put it on the floor.

The probability of scoring was 1/3 and 84 people won and 97 people lost.
