Query: waste of money

I did this with my 8 and 5 year olds. They were very excited about it- the box is very appealing. Sadly, there is more packaging than content. Kids lose interest after one "experiment." The "safe chemicals" are really just household items (you need to use your own anyway)- with a quick online search, you can make your own fizzy experiments. Any attempt to make this "educational" is a sham.Overall, a shameful attempt to separate you from your money
