Dear children, do you know that there is much interesting scientific knowledge in our daily life? For example, they exist in the kitchen, in the process of mom’s cooking. In fact, there are many scientific magics hidden in the kitchen. Now, we can make a lava lamp by the common ingredients in the kitchen. Such as water, vegetable oil, white vinegar, food colorings and so on. Do you want to know how these components can make the lava lamp which like the volcanoes eruption that under the water? Let's learn the principles of volcanoes eruption and basic chemical knowledge together through this kit, explore the mysteries of science!

Now let’s prepare the components that needed by the kit of lava lamp, we Alpha Science Toys will make the beautiful lava lamp with children!
