Note: the battery is not included in the set. The product is non-finished product. It need to be assembled by the buyer.
(1)DIY Ferris Wheel
Product material:Environmental protection plastic
Product size:26*9cm
Work principe:The principle of deceleration and force transmission is applied. When the power is turned on, the high speed and small torque of the motor are converted into the low rotation speed of the large revolver, and the high torque,so that the large rotation speed strongly drives the tourists to rise slowly and then slowly fall.
battery, screwdriver are not included in the set.
(2) DIY Electric Reptile Robot
Product material:Plastic
Product size:87mm*80mm
Work principle: After the circuit is turned on, the deceleration motor rotates to drive the crawler arm to move interactively, so that the "bug" is crawling.
Powered by 2 AA batteries (not included)
(3) DIY Electrostatic Snow
Product material:ABS plastic
Product size:90*75*86mm
Working principle: Principle of triboelectric charging.Frictional electrification is a process of contact and separation that causes a positive and negative charge imbalance. Friction is a process of constant contact and separation, so frictional electrification is essentially contact separation and electrification. In everyday life, all types of objects may generate static electricity due to movement or friction.
The product does not include batteries.
(4) DIY Four Wheel Drive Car
Product material: ABS plastic
Product size:120*120mm
Cognitive goal: The motor can be converted into the mechanical energy of the small pulley rotation. The mechanical wheel is transmitted to the large pulley through the pulley. The small pulley radius is smaller than that of the large belt, so it can bring lower rotation speed and greater driving force.
battery is not included.
(5) DIY Vacuum Cleaner
Product material:wood+plastic
Product include:Ice cream bar, double-sided adhesive, wood, and screws, motors, stents, propeller
Product size:25*6cm
Working principle: The motor rotates at a high speed, which drives the fan to exhaust the air from the bottle mouth to the outside of the bottle, thereby forming a negative pressure in the bottle, and finally generates suction at the mouth of the bottle, and the paper dust is sucked into the bottle.
Not included the bottles and AA battery
