Juniper scent
For our soap we had to make a scent that would smell good so I found some juniper
The scientific Method
Materials: Extractor, juniper, dry ice, vile
Experiment steps:
1. Chop up juniper so it will fit in extractor
2. put juniper in extractor
3. crush dry ice to fit in extractor
4. fill extractor all the way up with dry ice
5. seal it
6. wait for pressure to grow
7. once pressure is at 1000 set it up with the vile
8. start releasing the oil
9. put alcohol into vile to get it all off the sides.
Experience:
Because I had already made a scent this year it wasn’t as interesting but it still was pretty cool, especially because this time I got to work the extractor. after andrew left it was already almost done so I didn’t get to use it for very long but while I did I was scared I was gonna release too much pressure. after it all the air from the extractor still had scent so we walked around “Christmasing people up” which was just us spraying people because it smelled like christmas.
.
Science Behind It:
when you seal the dry ice it increases the pressure and once the pressure is high enough the dry ice turns into liquid CO2. Liquid CO2 is a very good solvent which means it dissolves the things around it and turns them into oil. So it is not the pressure that makes the oil it is the liquid CO2.
