If you’re cosplaying as a Dragon Age character, you can carry around the ultimate prop by making drinkable glowing Lyrium potion. Cosplayer Arkady made the drink and put together a tutorial detailing the process. It’s a pretty straightforward build, and the key component is a waterproof LED. Arkady used a corked glass bottle (you can get them at most craft stores), blue Gatorade, non-toxic glue, and waterproof LEDs. The LEDs usually glow for around eight hours. The first steps:
Clean your bottles and your LEDs.
Hollow out the inside of your cork with a knife or scissors. You want a little space for the LED to snugly sit in.
Attach the LED to the cork with a touch of non-toxic glue. Turn on the LED at this point too.
While the glue sets up, fill your glass bottle with your lyrium or potion.
It’s extra important to make sure the glue is non-toxic.

You could also apply this tutorial to League of Legends or World of Warcraft Mana potion.
