RAINBOW PAPER!

Kamusta! today in Science were doing two cool experiments, and one of those experiments are called chromatography Pens. So I'm gonna tell you how to do it, Here are some easy steps to do this cool experiments.

Aim - To separate the colours.

Materials:
- Chromatography Paper
- Pens - Red, Black, Green
- Ruler
- Pencil
- Water
- Plastic Cup

Steps:

1. Get a piece of Paper and mark the top of the paper about 2 cm and at the bottom mark 1 cm using the ruler.
2. Get the 3 color pens of your choice and mark it like this and fold the top where you mark it about 2 cm:

3. Get your plastic cup and hang your piece of paper in the side of the cup and pour some water inside just about the 1 cm where you mark it like this:

4. Just don't move it and wait about 5 mins or more for the colors to spread out.

Our ones failed because we used a black marker to mark the lines, and it affects the experiment.

That's All for Today! See you on our next cool chromatography experiments.
