EUDAX Fruit Battery Science Kit - DIY Classroom & Home STEM Clock Project (8-Set)

Unleash curiosity with the EUDAX Fruit Battery Science Kit, a hands-on learning set designed for students, teachers, and curious minds. Assemble a fruit-powered clock and light-emitting diodes (LEDs) using common fruits and simple electronics. The kit blends tactile exploration with clear, safe setup to nurture practical understanding of basic circuits, energy transfer, and experimental thinking.

What’s in the box

• 4 copper sheets
• 4 zinc sheets
• 2 RGB LEDs
• 2 red LEDs
• 1 electronic clock
• 4 wires
• 2 wires with clip

Key learning experiences

• Hands-on circuit building that reinforces cause-and-effect in electricity and energy conversion
• Visible feedback through LEDs and timekeeping, translating abstract ideas into tangible results
• Encourages experimentation with different fruits and solutions to observe performance changes

How it works in practice

In simple terms, inserting copper and zinc into a fruit or liquid enables a small electrical current. This current can light LEDs or run a clock, illustrating energy conversion in a real-world context. The color shifts of RGB LEDs provide immediate visual feedback as you vary the materials.

Ideal use cases

• Home study projects that spark STEM curiosity
• Classroom demonstrations to illustrate circuits and energy flow
• After-school clubs and science fairs to foster collaboration and inquiry

Care, safety, and tips

Rinse components after use, let them dry, and store sealed for next sessions. For best LED visibility, perform experiments in dim environments and supervise younger students. Follow the included guidelines for fruit selection and insertion depth to optimize performance.
