Taking inspiration from the game Bou-Toshi, Yukihiro Kaneuchi created a series of vases made of sand and resin.

The objective of Bou-Toshi is to keep a pole up that’s been placed in a heap of sand. Each player takes turns removing sand until the pole falls. If you cause the pole to fall, you lose. The vases resemble the heap of sand and the flower(s) placed in a glass tube would be the pole.
