Teacher Lei's Science Laboratory

I’m an engineering enthusiast focused on water rockets, science experiments, educational equipment, and original mechanical designs.
On this channel, I share the development, testing, and improvement of water rocket systems, launch pads, parachute deployment devices, science teaching tools, 3D-printed parts, and other hands-on engineering projects.
Many of the products shown in the videos are independently designed and made by us. Custom development, educational equipment, water rocket products, and project cooperation are available.
For product inquiries, customization, or purchasing, please contact me through the email or contact information listed on this channel.
