Conclusion
What have I learnt from this experiment?
I learnt that when you put colours on a filter paper and soak it in water the colour go's to the other side and makes a rainbow.
I learnt that the colour on the paper travels at different speeds
I also found out you can figure out DNA fingerprints/footprints.
