Our research of material for our idea(conclusion)

These balls are very cheap and cute ~~

They also come in many colours which are suitable for our game. However, they are too small.

Also come in many colours, but won't roll consistently.

This is the most suitable type of ball, firstly because of the size, secondly because of the weight (heavy enough so that it won't fly off the field easily) and thirdly because it is firm and bouncy.

This one is cheaper and we can spray paint them in different colours for our game. However, Ziyi already has some footballs at home.

This one is too expensive, please ~~

These basketballs are also too big and expensive and are not meant to be kicked.

When we discussed ideas, we chose to focus on Ziyi' s ideas because it sounds good, but we need to modify and improve it a little.

However, we decided and agreed on the main materials already so we went to the sports shop to check some out.
