Identifying the problem
The problem I identified is fire work safety. Kids are always hurting themselves when using fireworks. So I invented the "Firecracker Cannon". It a hands free way to throw a firecracker.
Brainstorm/Design/Blueprint
It will be supported by a Lego structure base/structure. The chamber is made of a medium wide marker with all the insides taken out. The arm that holds the chamber is adjustable for proffered angle
Research
Similar Ones have been invented but non have been adjustable.
Build/Gather Materials
The materials needed are:
Legos
Crayola wide marker
Wirecutters
Firecrackers
Lighter
Test and Evaluate
I tested this summer it works completely fine. But the chamber needs to be reinforced by layers of thick tape such as masking tape or duct tape. I beleive that it's completely safe and just flat out awsome.
