We think the thickeners in the milk are making the liquid unable to go into the Oreo

Types of thickener's: 

1. Next Milk has locust bean gum which is a sugar polymer from a Carob bean and gellan gum which is also a gelling agent made from bacteria it also has soy lecithin which is a emulsifier that keeps solids suspended in the liquid

2. Chocolate milk has carageenan which is a gelling agent made from seaweed 

3. White milk has no thickeners at all

4. Oat milk also has no thickeners

Controlled variable: Time, Oreo.

Manipulated variable: All Liquids ( 1 silk nextmilk, 2 chocolate milk, 3 regular milk 2% fat, 4 oat milk, 5 water)

Responding variable: How much milk the Oreo has absorbed.

1: Measure the weight of the before weight and write it down.

2: Dip Oreo in liquid and leave it for 30 seconds

3: Take out Oreo. Let it drip for five seconds

4: weigh an empty glass (same type of glass you are using) save the weight of the glass.

5: Subtract the weight of the empty glass from the new weight

6: Repeat procces for every liquid 

All of the Oreos came out different than before. The one that came out of the water came out not looking like a Oreo at all. The Oreo dipped in the Nextmilk absorbed the least amount of liquid followed by chocolate milk, oat milk,regular milk and water.

From what we have seen the milk with the least amount of thickeners have absorbed more liquid than the ones with more. The only one that does not follow this pattern is oat milk that had no thickeners at all but the oats could have made it thicker

In conclusion the Oreos dipped in liquids that contained thickeners absorbed the least out of all liquids. We believe this because the thickeners block the pores in the Oreos making the Oreos absorb less of the liquid. The ingredients inside the milk could have also blocked out the pores making the liquid unable to seep into the oreo

you could use this if you like your oreo soggy or dry, to know what to use for the perfect texture to suit you

time in the milk could have been slightly different due to not paying attention to the timer and taking a while to fish the cookie out of the milk
