Will this make a big mess if my child helps?

It can drip a little when pouring oil, but the soft towel under the bottle catches most spills. I usually let kids handle the dye and pouring with close supervision and have an adult do the tablet step. A damp cloth cleans oil easily if you wipe promptly.

Is this safe for young kids and pets?

The materials are common household items. Keep tablets out of reach and have an adult do the tablet drops since they fizz strongly. Place the finished lamp somewhere pets and small kids cannot tip it. If the bottle breaks, treat glass carefully and clean broken pieces right away.

Can I substitute anything if I do not have distilled water or baby oil?

You can use tap water; distilled water just keeps things extra clear. Vegetable oil works fine in place of baby oil. Avoid using anything that is not in the materials list because it may change how the lamp behaves.

How long will the effect last once I add a tablet?

Each tablet piece will produce motion for a few minutes. Smaller pieces give a longer, gentler effect. You can replenish pieces every few minutes to keep the lamp lively. It does not run continuously without adding more tablet.

What if my lamp looks dull or the blobs do not show up?

Try a brighter color or add more dye to the water. Make sure the food coloring is water-based. Also check that you left enough water in the bottle and did not pour too much oil over the top. A brighter LED base under the bottle helps the blobs stand out.
