We’ll try to avoid the obvious smutty jokes here... But it’s hard (No innuendo intended). First off, it’s horizontal, so you can use it for annoying flowers that don't last. Or for top heavy ones like hyacinth, peonies, parrot tulips - the glass supports the stems. And since the majority of the flower is underwater, the flowers will generally last twice as long. Last twice as long? Horizontal? Well, we did call it the Horn.
