We were investigating bubbles today.
We looked at what shape they are (interestingly, they are always spherical no matter what shape the bubble wand is), how big can we make them, what colours can we see, whether the bubbles change colours according to how close to bursting they are, how can we touch them (only if our fingers are wet, preferably with bubble mixture on our fingers), how can we keep them in the air?
We know the answers to all these questions.
Just ask us!
We also looked at the effect that the wind speed and direction had on our bubbles. Bubbles are really interesting to look at and to investigate.
