great visual with the soap! I know these were shown after 5 minutes of reaction, but I would've also liked to have seen the total time each reaction lasted. Will replicate to satisfy my curiosity

[@unclematt3]

Great idea with the soap. Makes it much more visual and easy for the kids to see.

*Proceeds to put 7 drops of detergent*

Hey she tried haha

[@walterkersting1362]

So how do we weaponize this?

[@pratyushlandekar9560]

Too weak

[@michelledeng3300]

what happens if you use grounded potatoes instead of solid cube potatoes?

[@caefunk]

More surface area = faster reaction

[@cutegirl5238]

What's role of Potato..??

[@keannafoster4560]

Yo what percentage of concentration of hydrogen peroxide did you guys use?

[@ashleypereira3133]

3%

[@FulvioItaly]

20%

[@MrJjsis]

this works with normal water ?

[@jollyranchu141]

Facepalm

[@katienicole8422]

no...H2O is water. H2O2 is hydrogen peroxide.

[@spookywizard4980]

thanks for the laugh XD

[@aleoon6311]

What role does the detergent play?

[@er4110]

measuring the reaction rate in the form of bubbles. Since the decomposition is 2 H2O2 --> H2O + 02 the bubbles are a good estimate of how fast the reaction is going.

[@Disco_Elysium]

easy to do with students as liver smells and too slimy

nice

[@totaaa9926]

This with h2o2 please replay

[@cloudytysm]

@@totaaa9926 what-

[@walterkersting1362]

I propose a fifth container with powdered potato flakes

[@nobody10011]

totally not using this for science fair in school
