Star - Bombshell - Hand Mold

Star Bombshell:

1. Prep your station
   Line a tray with parchment. Keep humidity under ~50% if you can.

2. Make your base
   Use your usual bath bomb mix and bind to a “wet sand” texture (squeeze and it holds, crumbles with a poke).

3. Pack a thin shell (Half 1)
   Lightly fill the star mold half. Press the mix firmly up the walls to create a 5–8 mm shell with a hollow center. Scrape the rim flush.

4. Unmold Half 1
   Tap the mold, lift off carefully, and set the shell on the tray.

5. Repeat for Half 2
   Make a matching shell and unmold.

6. Let the shells firm up
   Air-dry 20–60 minutes (or until they’re handleable without deforming).

7. Add the surprise core
   Place glitter, shimmer, embeds, and/or bath dust into one shell’s cavity. Keep contents below the rim so the halves can meet cleanly.

8. Create a clean rim
   Brush crumbs off both rims. Add a super-thin ring of fresh mix around the rim or lightly mist the rims with 91–99% isopropyl alcohol or witch hazel as “glue.” (Some makers use a tiny bead of bath melt or MP soap instead.)

9. Join the halves
   Align, press together firmly, and give a small twist to lock. Wipe the seam if needed.

10. Cure
    Leave on the tray to harden 24–48 hours (longer in humid rooms).

11. Finish (optional)
    Dust the exterior with mica or shimmer. If you use glitter/mica, include Polysorbate 80 in your formula to help disperse color and reduce tub ring.

12. Package & label
    Protect from moisture; note any small parts inside if you sell to families with young kids.

Troubleshooting quickies

• Seam cracks: rims too dry or uneven—re-mist and press again.

• Shells collapse: mix too wet or walls too thin—repack to 5–8 mm and let firm longer.

• Halves won’t stick: add a fresher, slightly wetter ring of mix or switch to bath-melt “glue.”
