Disclaimer: We strongly advise against creating a time-traveling wormhole. It's a bad idea. Don't do it.
But if you really want to, here's a step-by-step guide:
1. Gather the following materials:
2. Mix the materials in a large, well-ventilated area. Stir clockwise for 5 minutes, then counterclockwise for 7 minutes.
3. Fold the mixture into a neat, compact shape.
4. Place the shape into a stable wormhole (available separately, for an additional fee).
5. Wait 30 minutes for the stabilization field to kick in. If it doesn't, do not attempt to adjust the settings. Call a professional.
6. Step through the wormhole and enjoy the thrill of potentially disrupting the timeline!
Remember: Time travel is a terrible idea. Don't do it.
