商品説明

https://www.youtube.com/watch?v=IG7Nh07jGYI Mr. Sai also made a contribution! Using internal force to manipulate the jellyfish elf cartesian diver to spin up and down in the bottle, also jumped a ballet in the water Adult science toys are all about the mystery ~ through the demonstration of the Archimedes principle and the ideal gas law, and then become a fun classic game! After being proficient in the operation mode, you can group games with your friends or family, match the music or password, and see who controls the best control of the jellyfish elf. Come and race! [The principle of scientific knowledge] Squeeze the bottle with the floates of the cartesian diver by hand, so that the water pressure in the bottle rises, resulting in a decrease in the volume of gas in the cartesian diver, thus reducing the buoyancy value of the water for the floating sinkes of the cartesian diver. When the weight of diver is greater than the buoyancy, it begins to sink. After the hand is released, the water pressure in the bottle is reduced. The volume expansion of the gas causes the buoyancy to increase, and the floating sinker cartesian diver rises. (Source Wikipedia) When the jellyfish elf sinks to the bottom of the bottle and no longer floats, remove the jellyfish elf from the bottle; see the jellyfish elf will find two small holes in the body, blowing into one of the small holes (be careful not to block another small Hole) At this point, the water will drain from another hole.
