For young adults, basic chemistry kits would be of little value. However, toddlers are the best and closest thing compared to the real deal. The most important thing is it’s safe, and you don‘t have to keep a constant eye on them. As they grow, you can invest in a more realistic one if they are still interested. However, it is vital to give your time and attention while they practise. You can also make them interested in the way chemicals work in our everyday life, something that is very prominent in the kitchen. Make sure you go through the instructions of the set carefully and see if it asks for adult supervision at any stage.
