My name is Pieter and I am a mechanical engineer from Germany.
I want to share a recent product that I have worked on with you.
The project is called Spark To Go and it is a metal reusable water bottle with an integrated carbonation system inside the bottle.
This product allows you to make sparkling water everywhere you go and eliminates the need to buy plastic bottles from the stores.
It is currently pre-selling on Indiegogo. Go check it out if you want to learn more.
