Our Findings:
Vinegar = The whole shell was covered in slimy layers.
Blackcurrant juice = The whole shell bubbled and stained purple. Orange juice = The whole shell was covered in slimy layers.
Water & Milk = They stayed the same.
Energy Drink = Half was covered in crystal like scales.
Tea = It was stained a darker colour.
There was only slight improvements on the toothpaste side (left) apart from with the energy drink egg. On that egg only the scaly crystals only formed on the non-toothpaste side showing the toothpaste protected the shell.
Based on our observations, milk and water are the best for your teeth as the eggs showed no sign of change, they stayed exactly the same.
This has showed us the importance of brushing our teeth and drinking beverages like fizzy, sugary and acidic drinks in moderation.
