Playing with the idea of nature inspiring science, these Test Tube vases are designed as the ultimate showcase vessel for a single stem of a beautiful flower. Using thick and durable air line cable, each test tube hangs in its own holder. These are perfect for hiding a bloom in a small spot, or running a series of them across a window sill, or off the edge of your kitchen island or bar. Keep one at ‘kid height’ so the little ones in your life can plop in the flowers they picked out of the garden.
