I usually study with 3 hourglasses next to me, to better organize my speech. The one with white sand lasts for 3 minutes, the one with green sand for 4 minutes, the one with yellow sand for 5 minutes. I flip them and I start speaking, then I look away for a bit and watch them after some minutes to understand how much I spoke about something. I did the same thing tonight, flipped them, started speaking and watched them. Both the 5 minutes one and 3 minutes one had ended, the 4 minutes one did not. I checked to see if some sand leaked out but it didnt. I waited for it to end and tried again and it worked normally. What was it? Have I unlocked time manipulation or something
