Since it is a more modern era, they have to make do with what they have. Ouija boards from a yard sale, cards from Hot Topic, etc. Some have even figured out how to cast spells with odds and ends. They have developed apps that allow you to track how long curses last and phases of the moon. Some like to keep their potions in old water bottles so the nymphs won't attack them for not being eco friendly, and put little stick on gems to make them look cute

Notable things include
Spells that make it so you don't lose your phone (developed by 3 friends to help their teacher)

Casting spells via cards against humanity (developed by a very bored Nagix)

Casting via ddr (1 guy got really drunk one night)

Spells that make it so you don't wake up anyone when making food at 3 am (4 stoner bros)
