Happy Birthday on Water Synthesizer With MakeyMakey and Scratch

Instead of Flowers and Singing you can build this installation
as a big surprise for birthdays.

MakeyMakey
Scratch
Water
Watercolour
Coloured Paper

Define the tones and give each tone a color.

Find out how best to place the glasses for the notes so that you can play the melody with one hand. Make a sketch of the positions of the different tones aka colours. And then add the big form like a tree or flowers.

Place the glasses with the colored water according to your sketch. Then cut large circles from colored paper and place them under the glasses.
