I decided to make an oracle deck out of different flavors of Pop Rocks, obscured in generic envelopes:
The deck is shuffled, and then the querent picks an envelope.
The reader then opens the envelope and pours some of the Pop Rocks into the querent’s palm.
The querent then eats the pop rocks, and the reader prompts them to think about how the Pop Rocks taste, how they feel, whether the experience feels good or bad, etc.
I think this is pretty similar to a traditional physical oracle deck, and the envelopes are pretty easy stand-ins for cards. But I wanted to use Pop Rocks because they’re such an evocative candy, and it’s hard not to have a reaction to eating them. (I also think the different colors and flavors contribute to the experience.)
