We have spent a lot of time trying to make slime with no success and finally found a recipe which works. We have made several batches at youth club and now Abi has gone into slime production, so if you don’t want to make your own, she will do it for you for £1. Heres the recipes we’ve used and some pointers we have picked up on the way.
The basic recipe has come straight from The Steam Powered Family. I strongly suggest you go and check it out along with their safety tips, its worth reading their whole post to get it right first time, or you will most likely hit the same snags they did. Having said that the recipe is pretty forgiving, (I will put the amounts in a recipe below as UK measurements are a bit different). If you are in the UK however some of their branded ingredients are not so easily available. This is what we discovered works and a couple of things which don’t …
PVA CRAFT glue you can substitute any craft PVA Glue for Elmers glue
*Make sure you buy craft and suitable for children PVA as the builders grade has some extra nasties in.
Local to us glue from the craft section of Trago mills or Penhaligons work brilliantly.
Bicarbonate of Soda NOT Baking Powder. You can find this the baking section of any grocery store.
*If you put too much in the slime can become a bit lumpy
Buffered Saline Solution (must contain Borate/ Boric acid) -Our best brand so far is Superdrugs eyewash, it comes in a squeezy bottle so its easy to control the amount in your slime and on your hands.
Optrex also works well but you have to be careful when you pour it not to use too much and end up with non stretchy slime.
*Supersavers large bottle of buffered eyewash does not work, they sell a smaller one with borate in which would be fine.
Tempera Paint I used the food colouring listed on steam powered family and got blue hands, maybe I used too much? So we switched to Tempera paint,it didn’t colour our hands or anything else, washes off and is non toxic, win win. Also with a few prime colours we could make whatever colour slime we like.
*The only thing to note is that the colour intensifies as the slime is played with so factor this in when choosing your colour.
100g PVA (we found a large dollop in a bowl or on a plate works well).
1/4 tsp Bicarb
Paint to colour
Add a small squirt of buffered saline and mix,
It needs to start to ball in the middle of the bowl, a bit like this:
See the spoon ghost, she wouldn’t stop mixing to let me snap a photo, this stuff is addictive…
When it reaches this point you need to mix and play with it for about 5 mins. Put some saline on your hands before you pick it up and knead,it will me sticky but as the steam powered family say if you want the stretchiest slime this step is important. If you cut it short or add more saline to reduce the stick, your slime will not stretch so well.
After about 5 minutes you can add a tiny bit more saline to your hands and work it a bit more
Then when its not sticky any more you can call it done…
and its time to play,
Variations we have tried
Sparkly Slime – Glitter can be added with the PVA or after it has been made
Textured/ Crunchy slime – Polystyrene balls added after it has been made.
Fluffy Slime – equal amounts of with shaving foam with the PVA you will need to add a bit more bicarbonate of Soda and saline to balance the added volume.
Many colours – we found the more paint that was added the more saline/ bicarb needed to get to the ball stage.
How long does it last?
We found that the stretchier it was to start with the longer it retains its stretchiness.
Temperature affects it, if it gets cold it becomes harder then loosens with play.
Fluffy slime looses its fluff after a day and becomes more like the original slime.
Thats all for today folks.
