*Kikkerland Solar Radiometer

-
*I received this product for free but the opinions are my own.

The Kikkerland Solar Radiometer* demonstrates with simple physics and movement how light can be transformed into energy. The black and polished vanes are suspended in the semi-vacuum created inside the radiometer and when it is exposed to a warm light source such as the sun or a lamp, the vanes will spin.
Kikkerland Solar Radiometer

The more powerful the light source the faster the vane will spin. This works because the black side of the vane absorbs the light faster than the polished side, air pressure builds and raises the temperature of the air molecules on the back side of the vane which causes the spinning motion. Hopefully you can see how it works in the video I have included below.

The Kikkerland Solar Radiometer comes in 2 pieces, measures 4 inches x 3 inches and is really easy to slot together. You can use it as a science experiment with your children, or simply display it as an interesting conversation piece. Its also quite relaxing to watch it spin. The Kikkerland Solar Radiometer is available from Amazon for £28.28.

Primark Vitamin Enriched Moisturising Primer Review - Bobbi Brown Dupe

**Reposted as the Primark Vitamin Enriched Moisturising Primer is  currently reduced to £2.50 from £4.50. I picked up the Primark Vitamin Enriched Moisturising Primer because it looked like it was a dupe for the Bobbi Brown Vitamin Enriched Face Base. The Primark version costs £4.50 for 45ml and the Bobbi Brown Face Base costs £48.50 for 50ml, so there is quite a price difference.   I had always wanted to try out the Bobbi Brown product, so when I received a mini version in a gift with purchase goody bag I was really excited to try it out, but I have to say I was somewhat underwhelmed.  I have quite dry skin and the face base did not have as much slip as I was expecting, so it didn't feel smooth when I applied my foundation. For the price I was expecting to love it way more than I did. It does have a lovely lemon smell which I really enjoy, where as the Primark version doesn't really have a fragrance.  Overall, I actually preferred the Primark version as it is thicker and it ma

I have wanted to get an LED Mask for ages but with prices for some of them at over £400 I just haven't been able to pull the trigger and buy one yet.

Aldi Lacura Vitabase Moisturising Primer Review - Bobbi Brown Dupe

-
Image
I managed to get my hands on the newly released Lacura Vitabase Moisturising Primer from Aldi which is supposed to be a dupe of the Bobbi Brown Vitamin Enriched Face Base. It costs £5.99 for 50ml whereas the Bobbi Brown product costs £48.50 for 50ml. That's a big difference especially at times like these when every penny counts. The big question - is it any good? I actually really enjoyed using this primer. I have dry skin and this thick creamy primer really suited my skin. It contains vitamin c, vitamin b, vitamin e, shea butter, sodium hyaluronate & geranium oil and I found it very hydrating on my skin and it provided a great base for my makeup. My makeup stayed on all day and didn't go patchy or dry. It also has a fresh grapefruit and geranium scent which is really refreshing, but don't worry its not an overpowering smell. If you have dry skin I really recommend this product. It looks like its only available in store, so be quick as I'm not sure how long it will
