In a large pot, heat the oil over medium heat until shimmering. Add popcorn kernels and cover with a lid, leaving a small gap for steam. Once popping slows to about 2 seconds, remove from heat.

Transfer the popped popcorn to a mixing bowl. While warm, sprinkle with granulated sugar and toss gently to coat.

In a separate bowl, combine the flavored gelatin with hot water and stir until dissolved. Let it thicken slightly.

Drizzle the Jello mixture over the sweetened popcorn and gently toss to coat evenly.

Sprinkle coated popcorn with salt, adjusting to taste, and mix gently.

Spread the coated popcorn on a parchment-lined baking sheet. Allow to set at room temperature for about 30 minutes.

Once set, break into clusters and serve in colorful bowls or bags.
