EUDAX Fruit Battery Science Experiment Kit for DIY School Home Teaching Equipment, Orange Lemon Potato Electronic Clock Science Project Kit Physics Educational for Students Teachers (8 Set)

Build a Clock Powered by fruit battery, you need to read the instructions carefully and prepare the same fruit or solution, for example: apples, oranges, potatoes, lemons, tomatoes, cola, pears, pineapples, or salt solutions, etc. When the spreadsheet starts working, you will experience endless fun. You can also create a circuit with RGB LED lights, and let the LEDs emit different colors of light by changing different experimental materials Advantages: Through complete the fruit battery science experiment project with Student, it can create student's imagination, improve hands-on ability, increase scientific knowledge, and cultivate scientific invention hobbies 1 Set Package include: 4 X Copper sheet 4 X Zinc sheet 2 X RGB LED 2 X RED LED 1 X Electronic Clock 4 X Wires 2 X Wires with clip Product Maintenance:Remember to rinse with water after use,let dry and keep sealed for next use. Fruit selection：we suggest you use fruit with more juice, tomato will be your first choice, if you choose lemon and orange, please insert copper and zinc tablets in the same petal flesh (there is a membrane between the different petals that will hinder the transfer of electrons), as far as possible, insert copper and zinc tablets all the way into the fruit.The LED lighting effect is more visible in dim environments.

• 1 SET Package Includes: 4 pieces copper sheet, 4 pieces zinc sheet,1 piece Electronic clock,2 pieces RGB LED and 2 pieces Red LED,4 pieces Wire, 2 pieces wires with clip
• Easy to operate: you only need to prepare fruits, vegetables or drinks to assemble a battery to work with led or electronic watches, such as: apples, oranges, potatoes, lemons, tomatoes, cola, pears, pineapples, or salt solutions, etc.
• Benefit:By completing the Fruit battery Science Experiment Project , let student experience the mystery of science, develop thiers imagination and hands-on ability, and make them more interested in scientific experiments. Widely used in intellectual development, hands-on brain, interest training etc
• Usage and scenarios: This is a physics experiment equipment, mainly used for middle school students' home education or teachers for classroom teaching demonstration, if you show to Student younger than 14 years old, should be conducted under the supervision of teachers or parents.
• Notes：Read the instructions carefully before building the project to avoid damage to the electronic watch or to prevent the LED from working.The positive and negative polarity of the LED should be noted.
