1) Tiny Terrarium in a Lightbulb

What you make: A miniature greenhouse for tiny plants, moss, or air plants housed inside a glass bulb.

What you’ll need:
– An old incandescent bulb (empty and clean)
– Small tray or work surface, gloves, and eye protection
– Glass cutter or hobby knife, and pliers
– Sandpaper or a sanding drum
– Activated charcoal, small pebbles or crushed stone, potting mix
– Tiny succulent or moss, tweezers
– Drill or Dremel (optional if you’re creating an opening)

How to do it (high-level steps):
– Safety first: Wear eye protection and gloves. Work outdoors or over a protected surface.
– Empty and clean: Remove the inner components if you haven’t already. One common method is to gently crack or cut off the top of the bulb near the base, then sweep or rinse out the remnants.
– Create drainage: Place a thin layer of pebbles at the bottom, followed by a pinch of activated charcoal to keep the environment fresh.
– Add soil and plant: Add a small amount of potting mix. Use tweezers to seat a tiny succulent or some moss.
– Finish and display: Clean the outside, dry, and place in a spot with bright, indirect light.

Tips and variations:
– For a low-maintenance version, use moss only or a tiny air plant, which doesn’t require soil.
– If you’re not comfortable cutting bulbs, you can purchase ready-made pre-cut bulb terrariums from specialty shops or craft sellers and decorate those.

Tips:
– Keep it hydrated for a short period; use a short stem to keep the overall balance light.

Safety considerations and best practices

– Environment and recycling: If you’re dealing with old CFLs or fluorescent bulbs, these bulbs contain small amounts of mercury. Do not crush or break them indoors. If you’re unsure which bulbs you have, or if they are compact fluorescent lamps (CFLs), consider taking them to a local electronics recycling facility or hazardous waste program rather than attempting DIY repurposing that involves breaking the glass.
– Handling glass: Always wear safety goggles and gloves when cutting or breaking bulbs. Work on a protected surface and consider using a thick cloth or towels to cushion glass fragments. Keep a broom and dustpan nearby for clean-up.
– Cleanliness: After breaking bulbs or removing insides, thoroughly wash your hands and any tools that contact the glass. Avoid contact with eyes, mouth, or skin if you’ve cut yourself on glass.
– Finishing touches: For some ideas that require sealing, ensure you use a silicone sealant or epoxy that is rated for glass and for indoor use. Allow adequate curing time before handling or displaying your project.
– Stability: If you’re turning bulbs into hanging pieces, ensure you have a secure hook, string, or fixture. Bulbs can be delicate; weight distribution matters so it doesn’t tip or fall.
