I've narrowed my idea down to two.YAAY:)
so, ive got
" which brand of soft drink will affect our teeth the most?"& " effectiveness of blu tack holding up a poster in hot conditions"
For the first idea. I could substitute the teeth for eggshells or chicken bones. I will choose 4 popular drinks such as coke,
sprite, fanta and pepsi.
For the second idea. I could use the hair dryer to use as a substitute for heat. i would observe the changes made from normal condition to hot dry conditions.
just which one to choose ....?
bye for now ,not forever
