This is a simple experiment using sodium polyacrylate which is a super absorber and can absorber up 200 to 300 of its owned mass of a liquid sodium polyacrylate has the formula of COONa molecular -CH2-
This is a simple experiment to perform just add a few grams of sodium polyacrylate to water warm water works better (email me if you want amounts firstname.lastname@example.org)
Sodium polyacrylate can be bought from most chemical suppliers or in shops or internet as "fake snow"
colour change experiment
This is a simple ph test
for the 1st part of the experiment you will need universal indicator and an acid and base most acids and base’s will work as long as there strong enough first make a water indicator solution than just simply add some of your acid to get a red colour then simply add your base drop by drop while stirring or shaking to get all the colour of the ph scale 1 - 14 when you get to a ph of around 14 just do the experiment the other way around by adding the acid drop by drop. for the second part of the experiment simply make a phenolphenel solution add a strong base to turn it pink then add a acid to turn it clear again
