Practical 4
Introduction:
For this practical session, we conducted the practical once again in the FabLab in Singapore Polytechnic. During that practical, we were given 2 hours to construct a game or toy using cardboard. We were able to make a fully functional and working toy using the different cardboard joineries that we learnt from the previous practical (Practical 3). We were then given 5 minutes to present our toy. We were also given 2 ice cream sticks each which represented our vote, to vote for the best toy that we like.
The toy that we created was a fully functional and easy to play “Air Hockey” (Figure 1), that is made out of cardboard.
Figure 1: Air Hockey

Thought Process
The team wanted to create a fairly easy and fun filled game for the Primary 4 students. Hence, why not the class “Air Hockey” that everybody loves to play at the arcade? We decided to bring this idea and construct it for this practical assignment. The components that we have created to form this fully functional “Air Hockey” game consists of 2 Pucks ( 1 Green and 1 Red to separate the two opposing players), the arena for the game, 2 goal posts as well as a scoreboard where the first player to reach 3 goals wins !

How to play the game
As seen from Figure 1, the hockey strikers represent opposing teams with different colours, green and red, the player will hit the marble ball and try to hit it into the goalpost while the opposing player tries to defend the goal and prevent the other player from scoring. The objective is to hit the ball into the goal and the first player to win three points wins the game. The purpose of the scoreboard is to keep track of the scores of each player.

Our presentation
In our short presentation, we have explained the gameplay and the joinery methods used to make this hockey game.

Joinery
For the air hockey strikers, we have used score + bend to create the circular shape of the strikers. For its handles, we have created slots to create an x-shaped handle for more grip. As for combining the sides of the air hockey table, we have created slots so that the table would not fall apart during play which may be vigorous. We have also used slots to slot the ‘netting’ in the middle of the table. As for the scoreboard, we have created a gusset to support and stabilise the scoreboard while showing the scores clearly. On the scoreboard, we have used cable ties to hold the score cards all together while making it easy to flip as the score number changes.
