What liquid will rust metal nails the fastest?

Report
By: Leah Critcheloe and Taralyn Taylor
Purpose
The reason we are doing this project is to find out if Sprite, Orange juice, or Milk will
rust nails and if it dose witch one rusted the fastest ?
Hypothesis
We think that the sprite will rust the fastest because it has citric acid in it and that
might make it rust faster
The Materials
● 9 red solo cups
● 9 large metal nails
●12oz of milk
●12oz of sprite
●12oz of ocean spray
orange juice
●1 silver sharpie marker
Procedure
STEP 1: Take out three of the solo cups and write O.J, Sprite,
and 2% Dairy Milk, do this three times.
STEP 2: Pour the 2% dairy milk in the cup labeled milk, do
the same with O.J, and sprite with correctly labeled cups.
STEP 3: Put 1 nail in each solo cup.
STEP 4: Take out the nails everyday for three days to check
for rust.
1=little to no rust
2=some rust
3=most rust

My conclusion
The liquids didn’t have enough time to rust. Sprite
and orange juice must have had some acid in them
because they did the most damage. Milk did little
damage. Our hypothesis was right because the
Sprite produced rust. We could have used a
different liquid, used teeth, or gave it more time.
