This Big Stream Somen Slider Galaxy is one of their cooking toys. Originally they released a set of Nagashi somen every year, and gimmicks have become more complex year by year, and this year's feature is "weightlessness". Usually, Nagashi somen flows from top to bottom according to the slope of the waterway, but Big Stream Somen Slider Galaxy jets the water stored in the "Mars-tank" with the power of the motor, puts the noodles on top of it, and flows it from the bottom to the top. The noodles run up through a transparent tube called the "hyperdrive-tube", so you can see the noodles rising and flowing. It ’s just like "weightlessness".
The body size of this is 792mm × 217mm × 460mm, and works with three D size alkaline batteries. The price is 10,778 yen (including tax), but you can buy it cheaper at stores and mail orders.
