Which Glass Will Fill Up First? Try to Figure It Out in 30 Seconds or Less

Let’s share the original image below so you can give it one more shot.

• Outlet to Glass-1 & 5 is blocked at the initial point, so they won’t fill.
• Outlet to Glass-2 is blocked at the endpoint, so it won’t fill.
• Outlet to Glass-3, 4 & 7 is also blocked in the middle, so they won’t fill.
• Nothing is connected to Glass-6.

Because of this, no glass will ever fill.
