Feature

• It is a special plastic bag that can conduct water synthesis experiments safely, effectively and easily.
• When a small amount of hydrogen and oxygen (20mL: 10 mL) is added at a ratio of 2:1 and ignited with the attached piezoelectric igniter, the inside of the bag becomes cloudy with a loud reaction noise, and it can be confirmed that fine water droplets are formed.
• Even if it gets torn, it is safe because it is a soft plastic bag.
