girlI suppose this one is probably more for the girls, so please go all out with the glamour – fluffy slippers, glitter and if you’re feeling very generous, substitute white lab coats for white bathrobes! Unlike other spa outings this party of course has a twist. The kids will get to do some science experiments which will be lots of fun. They’ll also get to take their concoctions home as favours, so you’ll save lots of pennies in that department too.

The Invite

Rather than send a traditional invite, get creative instead. This is a lovely invite idea I spotted on “One Charming Party”. In fact she has lots of fantastic ideas for the decor if you want to do it yourself. I suggest you take a look if you want to throw a great party.

Other ideas could be attaching a small paper invite to a small bottle of bubble bath, or nail polish, or putting the invite in a lovely box with tissue paper.

The Party

A popular idea I’ve noticed is to have stations around the room or house. Each station catering to a different activity. This of course is great for a science spa party as you want room for the various science experiments.

There are lots of ideas for decorations and food online. A few include small bottled water, cupcakes, get healthy with sandwiches cut into small triangles (in fact it seems anything on the small, cute side seems to work). More ideas can be found here.

Science Spaaah!

Fizzy Bath Bombs

This is an easy to follow, kid friendly way to make fizz bombs. It is from Soap Queen TV and she has lots of videos on  DIY soap and bath related projects.

You may want to make (or buy) some bath bombs beforehand so you can show what happens when you drop one in water. Ask the kids what they think is happening to cause the fizz. The answer is that the water triggers a chemical reaction between the citric acid and baking soda (bicarbonate of soda). Carbon dioxide is created during the reaction and it is this that causes the fizz. It is a simple example of an acid-base reaction. Any fragrance or oil you add to the bath bomb just helps make the skin smooth and scented.

Colourful Bath Salts

– 1 cup of Epsom salt

– 1 cup of sea salt

– colourants (from a crafts store)

– essential oils (different scents)

– air tight containers

– liquid soap

Combine your salts, a few drops of colourant, and a few drops of essential oils. Mix it all together so the colour is even throughout. Pop the salts into the air tight container and it’s yours to keep until you want to relax and unwind in a nice warm bath.

For the Science – get the kids to wet their hands with water, put a little soap on them and rub them to form a lather. Get them to note how much lather is formed before they wash it all off. Now fill a large bowl (or sink) with water, add 1/8 cup of the newly made bath salts and get them to mix with their hands. Once the salt has dissolved and their hands are still wet get them with salt water, get them to add a drop of soap to their hands for rub again. Now, how much lather is formed?

The kids should find more lather produced when using the salt water and this is because of the difference between hard and soft water. Hard water which is common in American households has a high mineral content, usually magnesium and calcium ions. These ions bind to soap particles and form an insoluble gray material, known as soap scum. This means you need more soap to get clean. It is also the reason why you see a layer of soap scum in the bathtub after you’ve finished a bath. So what does the salt do? Salt is made up of ions too but these are sodium and potassium ions. These ions replace the calcium and magnesium ions in the water, allowing the soap to lather more easily. It converts the water from hard to soft.

Another science phenomenon occurs when you add salt to your bath tub – osmosis. This is the movement of water from an area of high concentration to an area of low concentration. Our body has a mixture of water and salt and thus we have a lower concentration of water than a bath tub full of salt-free water. If we’re in this kind of bath we may notice our skin start to wrinkle (“pruning”), this is because the water from the bath is entering through our skin in an attempt to balance things out. If we add salt to our bath water, there is less difference in concentration between the bath water and our body so we don’t get this excessive movement of water and thus don’t wrinkle.

Lush soap

Making soap the true way includes lye and I would not recommend this for a kids party as it is dangerous. Therefore, I’d recommend you go for this kid friendly version. The great thing with this version is that the kids can include their own little trinket in the soap too.

*You may want to explain that the soap that we buy at the store is made when an acid and a base react together to form a salt (a process known as saponification) and it is this resulting salt that’s basically soap.

– Glycerin soap (found at craft stores)

– Molds (preferably silicone)

– Small plastic toys (as decoration)

– Food coloring (optional)

– Rubbing alcohol

**Note, it is good to rub the toys with rubbing alcohol before you drop them into the soap.

Melt the glycerin in the microwave. Add a few drops of food colouring into the melted glycerin and then pour into the molds. Get the kids to drop the small toys they like into the soap and then store the molds in a cool, dry place so they can solidify. Once cooled you can take their soap out and the kids can take home in their lush soap bars away in their party bags.

Here is another step by step guide on the “Skip to my Lou” blog.

Make you own lipbalm

I like this video – it is short and to the point. As you’ll see it is really easy and this is something the kids can easily do at a party.

As she is making a two-tone lipbalm she has included colouring. You don’t have to include that and you don’t have to get as carried away with the packing!

You can get the kids to experiment by changing the quantity of beeswax or oils.

So what’s going on?

Well lip balm is used to prevent chapping by providing a protective layer for the lips. Each of the ingredients has a role:

Beeswax thickens the lip balm and helps the other ingredients to stick together.

Almond oil is an emollient, which means that it softens and moisturises your skin.

Honey is also an emollient and tastes nice.

Essential oils flavour your lip balm and make it smell nice.
