I like to flavor my iced tea with freshly-squeezed lemon.
Usually, I squeeze the lemons with a tool that catches the seeds, but sometimes I’m in a rush and squeeze them by hand, dropping the seeds into my tea.
This usually isn’t a problem. But when I drink my tea with a straw, sometimes the seeds get caught in the straw, and I have to work them out from the straw with a series of squeezes.
Or, with a great gust of breath, I can shoot the seed across the room and out the sliding glass door to the patio.
