This kit allows kids to explore the Science behind acidic & basic solutions using purple water. A great one to do indoors and gives kids hours of play time. Please note the colours of the experiment may be different depending on the solutions in stock.  Purple water can be stored in the refrigerator for up to 7 days OR can be frozen for up to 6 months. Our tip would be to, upon receipt,  aliquot the purple water into smaller volumes and thaw what is needed.
