My family loves to go to Divisoria Mall. It is the best place to buy stuff not only at affordable prices but really at its cheapest. There are many Koreans and Chinese business owners there who introduce different products from their county at low prices. This place is also the best choice to buy not only toys for kids but also it is where new toys being introduced to the market.
A stuff that caught my attention is this crystal boll made in China. Wife bought 1 pack of it with more than 20 small packs in it. It contains very small colorful balls that according to her once submerge to water will expand or grow bigger. What we did is to fill a container with water, about ¾ of it, and then put all these little balls inside. As hours and days pass by it do grows gradually and as we continuously put water in the container it absorbs the water and increase in size. I do not know what exactly the reason why from such very small pieces of colorful will turn into big ones. But I must admit I like the colors and its appearance looks like a "sago" for me. It looks delicious to eat but forbidden of course.
Another good thing about it is that it can be transferred into a clear glass or plastic container and you can put a plant on top of it. The plant will not die as it gives oxygen. Something kids will find interesting to study on their Science subject.
