What substances will Drano actually eat through? -Libby Weber
Equipment: Required for this experiment is drano, test tubes, water, and various substances to test upon.
Procedure: Take each substance one at a time and apply drano to it, observe and record results. Dilute with water before disposal.
|Object||Effect drano has upon it|
|Human hair||Noticeably dissolved some of the hair, however, hair remained clogged in the test tube.|
|Bullet Casing||Nothing real noticeable changed with the bullet casing initially, however, after about 10 minutes, the casing looked slightly shiner.|
|Paper Napkin||no noticeable effects|
|Black snake fireworks||After roughly 30 minutes, color change from charcoal black to white and noxious gasses were noticeable.|
|Used tea grains||no noticeable effects|
|Daddy longlegs spider||Initially there was no noticeable effect, spider died after about 1 minute. Within 2 hours, the spiders legs were dissolved.|
Conclusion: It was apparent that the drano didn't really 'eat' through anything, rather, it was with prolonged contact with the drano that actually causes substances to dissolve. It is also observed that it is not readily predictable whether or not the drano works better on organic materials or inorganic materials.
