Try to bring your drawing to life

Have you ever wanted to see your drawing come to life? Animating a drawing without software is possible. A man, a boat, a message, whatever as long as it moves afterward. This feat you can also do at home, with dry-erase whiteboard markers.

Let's experiment

draw with a permanent marker in a dish

Place your white ceramic dish on a table and draw a shape you like with dry-erase markers. You can draw a boat, a bat, or just a man.

Let your drawing dry on the surface of the dish.

With the measuring cup, cover your drawing with a bit of water.

the drawing comes to life

Wait a few seconds, and then stir the water gently by moving the dish.

What happens? Does your drawing come off? Does it float to the surface, or does it stay on the bottom of the water?

Now draw with the permanent marker in the ceramic dish. What happens when you add water? Does the drawing come to life? (Be careful, ask your parents to clean the dish with the alcohol)

Funnily enough, when you pour a little water on the drawing made with the erasable marker, you can see that it comes off easily when you move the water. Plus, it floats. If you blow slowly on it, it even moves on the surface of the water. The same observation is made as for the aluminum foil, although your drawing seems more fragile.

On the other hand, the drawing remains well attached to the paper towel.

When drawn with a permanent marker, your design does not come off. To remove it, you must use a solvent such as rubbing alcohol.

Understand the experiment

Oops, I slipped, boss! 

The ink composing erasable markers contains the color pigment, alcohol to dissolve it, and an oily compound called silicone. When you draw on a smooth surface, the alcohol evaporates immediately. Your drawing dries instantly. However, the silicone in the design prevents it from “sticking” to the surface. That’s why you can easily wipe the picture off with a piece of paper or loosen your drawing with a bit of water. In other words, your drawing “glides” on smooth surfaces.

Your design makes the board.

Not only does your design come off, but it also floats and moves as if it were alive. The silicone in the ink of the erasable marker keeps your drawing from sticking to the board. That allows water to slide underneath it, loosen it and bring it to the surface.

You can see the same effect on aluminum foil, except that your drawing is a little more fragile.

On the other hand, the drawing made with a permanent marker stays at the bottom of the water. The ink that makes it up sticks firmly to the surface, so water cannot get underneath to remove it.

Household alcohol cannot be drunk or inhaled. Parents can only use it to clean the equipment.


The tree leaves are red

The leaves of trees are green in daylight. It is thanks to chlorophyll, an important molecule which is involved in photosynthesis to convert carbon dioxide into oxygen. But under black light, chlorophyll is red. A phenomenon linked to fluorescence. […]

The color decomposition of your markers

The primary colors are cyan, yellow and magenta. Three colors from which all others derive. One way to find out what the color of the felt-tip pens is made of is to play with water, a coffee filter and use the principle of capillary action. […]
