Hi all, one of the small issues I'm facing now is the coolant water is evaporating overtime, that is I guess to the design of my machine which has an open top tank under the t-slot table, that is to allow the coolant to collect from all sides of the table because its smaller than the tank and there are gaps.

anyway if anyone seen these before https://www.google.com.bh/search?q=a...w=1436&bih=782
I thought of using a similar concept, if it works will it be ok to use plastic balls in the coolant or will it react? or if anyone has any other suggestion please let me know, thanks!
