My previous posts about magnets and British coins met with a great response! I've been able to find some small magnets and I have relieved several Brits of their life savings in small coinage

Thanks to everyone who helped me to locate these items.

My next quest is for books of Ph paper. These are typically used in school science experiments to gauge how acid or alkaline a liquid is.

My initial point iof call was to a swimming pool supplier, but so far they all responded that they use more sophisticated means to measure the water Ph value, such as mixing tablets etc.

Does anyone know where I can buy simply strip books of Ph paper?

Thanks

Hi Simon.... maybe try an aquarium/fish shop?

Try garden or plant centre they may have soil testers.

Suksapan shops, maybe you can order online:

Industrial chemical suppliers to hotels, Ecolab etc......

You may be able to get phenothylene and make your own ph strips. Similar in effect to litmus.

There is a lot of educational difference between using phenolphtaleine (with which you cannot test acidity anyway, only alkalinity) and a proper pH test paper.

Well maybe he should use cabbage water.

Although he can test acidity with it. It is colourless in the presence of an acid.

Quick way of teaching the students not to lick their fingers

I know you are very qualified to teach science,,,I wish you were teaching in my nieces new school (why not move to Chiangrai they pay round 35000 and are advertising) but you may not have seen this which may help with lack of materials.

Try asking for Litmus Paper.
