Make a DIY Snow Globe!

If I can't find clear waterproof sealant or a small plastic figurine, what can I use instead?

If you can't find clear waterproof sealant, use a clear waterproof epoxy or aquarium-safe silicone caulk to glue the figurine to the inside of the lid and to seal the lid edge, and replace the figurine with any small waterproof plastic toy or sealed wooden charm that fits on the lid.

My snow globe is leaking or the figurine fell off — what likely went wrong and how do I fix it?

Leaks or a detached figurine usually mean the jar or lid wasn't completely clean and dry or the sealant wasn't applied properly, so rewash and fully dry the parts, re-glue the figurine using the recommended amount of clear waterproof sealant, apply a thin bead around the lid edge, and wait the full drying time before screwing the lid on and shaking.

How can I adapt this snow globe activity for different age groups?

For toddlers (2–4) have an adult do the gluing/sealing and let them pour water and drop large non-toxic confetti, for school-age kids (5–10) let them wash, fill the jar about three quarters full, and sprinkle glitter with supervision while an adult handles the sealant, and for older kids (11+) let them experiment with adding glycerin, trying distilled water to reduce cloudiness, or designing painted lids before sealing.

What are some easy ways to extend or personalize the snow globe after finishing the basic steps?

To personalize and improve your snow globe, paint or decorate the lid, tie a ribbon around it, swap glitter colors or add tiny sequins, mix a small amount of glycerin into the water for slower snowfall, use distilled water to keep the jar clear, or mount a small LED base under the lid before sealing for a glowing effect in photos and videos.
