Hot Air Balloon(2)

we used tissue paper and wires to make the air balloon

Here are our lovely group members~

Basiclly, the structure of our hot air ballon is based on the chinese sky lantern, it's a cylinder shape that is more stable.

We use tissue paper  because it's light and it would be easy to fly, but we forget the weight of wires..........TAT

unfortunate our balloon failed .........but it still kept in a good shape! I believe it was the best looking of all designs~

 I dont know why they made a hole there......it lose hot air...that's one reason for it's uncessceful.

 We put the candles at the bottom of the balloon, the hot air would go up and fly the balloon.

See!

 

 

 

Improvement: the biggest problem is the weight of the balloon, it was too heavy. We should make it lighter, and the candles were not enough~
