DISCUSSION

Why we choose plastic bottle ? How warm and cold air How many blades should a

- It easy to be shaped.
- It become soft when heated When blow with wide open mouth, The more blades a fan has, the

environment will not polluted.

DISCUSSION

For the best result :

1) Use in a room that is
not too spacious

2) Suitable for use when
studying in the room

3) Distance within two and
half feet from the fan

CONCLUSION

In conclusion, this eco cooler is an interesting idea to try and design. This is because
the items to create and produce are items that are very easy to find especially around
our homes. Therefore, this eco cooler becomes an eco-friendly design because we only
need to use used items. In addition, we can also reduce waste and waste disposal
because the items to produce this eco cooler can be used and recycled. The eco cooler
also has a role to increase the coolness without having to use a lot of electrical
energy. Therefore, the eco cooler also has a cooling function without having to waste
electricity consumption.
