Draw with a torch and the lines glow, then fade on their own. The board has a light-storing surface: run the pen across it and it leaves a bright trail that slowly disappears over about half an hour, ready to draw again.
The mess problem, solved sideways
The reason this gets used more than paint or markers is that there is nothing to clean up and nothing to run out of. No ink on the table, no paper to fetch, no drying time. A child can pick it up for four minutes before dinner, which is exactly when most craft materials are refused.
It also works the other way round from ordinary drawing — the darker the room, the brighter the picture. That inverts a rule children think they know, and the first time they take it under a duvet is usually the moment it becomes a favourite.
How it works
- Draw on the board with the light pen — brightness depends on how close you hold it and at what angle
- You can't rub anything out, but you can draw over it, because each new line lands brighter than the last
- The whole picture fades by itself in about 30–40 minutes
- The pen's other end is an invisible-ink pen for paper, revealed under the same light
What's in the box
- One glow drawing board, A4 size — big enough for a proper picture, small enough to hold on a lap
- One light pen with invisible-ink tip
- One template
Age guidance
4 and up. Four scribbles and is delighted that it glows. Six draws recognisable things and works out that holding the pen closer makes a brighter line. Eight uses the invisible-ink end for secret notes, which is arguably the real product.
Materials
Moulded plastic board and pen. Don't shine the pen into anyone's eyes, and keep the drawing sessions to fifteen or twenty minutes at a time. Store the board somewhere dark between uses so it holds its charge.
Frequently asked questions
How big is the board? A4 — the same size as a sheet of printer paper.
Does the drawing stay? No — that is the point. It fades on its own in roughly 30–40 minutes and the board is ready again.
Can they draw on it with a normal pen? No. Only the light pen, or the surface is spoiled.
Does it need a dark room? It works best in a dim one. Full sunlight washes the lines out.
