2. Our experiment
In our experiment, we tested if dry ice would sublime faster when it is in hand sanitizer. The hand sanitizer brand we used was called levels. To test how fast dry ice sublimed, we put dry ice in three different cups. Dry ice #1 had no hand sanitizer, dry ice #2 had 3 squirts of hand sanitizer, and dry ice #3 was fully submerged in the hand sanitizer. My hypothesis was that it would sublime fastest when it was submerged, and Nia’s was that it would sublime fastest with no hand sanitizer.

3. Which ONE sublimed the fastest?
Dry ice #3 (fully submerged in hand sanitizer) sublimed fastest. #2, the one that had a couple squirts on hand sanitizer, sublimed the second fastest! #1 sublimed the slowest and had no hand sanitizer.

4. After a while…(each weighed 8 ounces at beginning#1 #2 #3
15 MIN- 6 ounces
15 MIN- 5 ounces
15 MIN- 2 ounces
30 MIN- 4 ounces
30 MIN- 0 ounces
50 MIN- 3 ounces
50 MIN- 2 ounces
ZERO, JUST HAND SANITIZER
WE STOPPED
THE EXPIRAMENT
!!!

Conclusion
Dry ice sublimes fastest when it is in hand sanitizer
