- DIY mini vacuum cleaner assembly toy, exercise child's hands-on ability, understand simple circuit and mechanical transmission.
- Working principle:
- The motor rotates at a high speed, causing the fan to discharge air from the bottle mouth to the outside of the bottle, thereby forming a negative pressure in the bottle.
- All of our small technological toys are made of children's non-toxic ABS material, with a smooth surface without burrs, which is absolutely safe for children. Facts have proved that learning through games is the most effective teaching method for young brains.
- By assembling and constructing small technological productions ranging from simple to complex, this STEM toy can not only cultivate the mechanical skills of your young engineers, but also stimulate their imagination and creativity. This is a great educational gift for children.
