As SWIJawah mentioned volumetric dosing, SWIM
's hamster would like to mention a few words.
is a very stable chemical compound. Storing in the fridge in solution would probably be the best course of action once in solution, just to ensure a stable temperature.
Second, as SWISynthesised mentioned not having any scales. The hamster knows that if something, like say sugar or salt, is in solution, it should be equally distributed and suspended in the solution. Especially if one always follows "shake well before serving" rules.
So, imagine if a normal hamster had 500g of sugar and no scales, he would mix it in 1 litre of water, the hamster would be assured of .5g of sugar being suspended in every 1ml of the water solution. This is an easy method of dosage calculation.
So, Mr. Hamster says go forth and mix your hamster treats in your sports drink, fruit juice and remember the proportions
. If there is more than he would like to use in one session he would simply use the volume of liquid with his treats in suspension to the correct ratio. Then he could save the rest for another time in the refrigerator.
However, a word of caution, if one were to put something into a liquid suspension and store it in the refrigerator, MAKE SURE IT IS OUT OF REACH of anyone unsuspecting, or children. This could have very nasty or unexpected consequences. Be EXTREMELY careful if any hamsters intend to do this. The headlines on the newspapers could be very ugly.
Be safe, be careful, and have fun.
