Waves in a Bottle - Relaxing Toy for Kids

What ?

Very relaxing and easy to make toy - waves in the bottle.

What will be needed ?

Water & dye (watercolor for example, or food dye)

Bottle

Transparent Oil (baby oil is ok)

Making ocean is really simple ;-) Just pour the water to the cup, mix it with the paint and then pour mixture to the bottle.

Now pour the baby oil to the bottle and close it very good to avoid any leaking during play

That's all.It was really easy. Now turn the bottle and watch how waves are emerging.

I recommend You to watch the video I''ve attached to this instructable because pictures doesn't show how beautiful and relaxing could be the waves.
