On Scientific Explorer kits

Scientific Explorer is a company that makes science and cosmetic kids aimed to children. I have so far bought 3 of their kits: the Spa Science Chemistry Kit, the Perfumery kit and the Mind Blowing Science Kit for Young Scientists. I’ve been all in all happy with the kits, though a little bit concerned that they are expensive for what they offer – in particular because so many of the ingredients they come with are things you have at home anyway. For example the Spa Science kit comes with oatmeal and baking soda. That said, some of the ingredients they come with (e.g. the plastic vials in Perfumery or the red cabbage juice powder in Mind Blowing Science) are not so easy to otherwise obtain – or you would have to buy them in such large quantities that it’d end up being more expensive.
My gripe with Scientific Explorer is that while the contents of each kit is printed on the back of the box, you can’t find it anywhere else. For example, I was thinking of making sugar polish with the girls – I think Mika might actually like that – but all the recipes I’ve found online (e.g. these ones) require the purchase of different oils. I’m sure that when I added up the price of each one, the end result would be quite expensive. So I’m thinking I could get Scientific Explorer’s Sugar Polish for Your Body Make It Yourself Spa Kit, but I’d like to know what comes with the kit. Does it contain small portions of all those oils? Or does it just include sugar and some scent/essential oil? I’m worried because while the recipes I’ve found for salt rubs on the internet (e.g. these ones) also contain a number of oils, the recipes for salt rubs in the Spa kit consisted basically of mixing coarse salt with an essential oil. I don’t need a kit (in particular a $20 kit) to do that.
Some of the kits, like the Spa Science and Perfumery ones, are available at local stores like Target – so I can go and look at the boxes. But others, such as the Sugar Polish one mentioned above, are only available online. And while it’s sold by tons of places – none of them have a list of the contents.
So, in my next post I will post a list of the ingredients in the Spa Science kit (the ingredients in the perfumery kit are mentioned in my review of the kit).
