Firy is the homemade fire extinguisher. It is very cheap to build, efficient and reusable. It is very handy when there is small fire.
Step 1: Things You Need
Vinegar and water
Small plastic box

I used plywood to make a triggering part and holding part. The small plastic box is used to fill the baking soda when trigger is move upward the strip with hole moves and banking soda is release into the vinegar and water solution. And reaction create CO2 which is release from the hose.

- Use the trigger.
- Shake the bottle.
