Start by heating water to 62°C or 143 Fahrenheit

Pour the polymorph plastic pellets into the water and wait until transparent

The plastic hardens when it cools down, if it gets too hard to work with just reheat it

When it clears up just scoop it up, be careful it’s hot

Cut a small piece off, and dye it with food colouring for the gums

Ellis piece cooled down too much so she had to reheat it

Split the piece in two, leave one in the water

Use the other one to make a tiny sausage

Dry your teeth and place it over your teeth, make sure it sits properly

Wait a few minutes to let it set properly

Take it out, it’s okay if it’s still a little soft

You can trim off some excess pieces if you like

Now we make teeth with the clear plastic

Shape your teeth, use scissors to get them really sharp

Make them any size you want but not too long or they will hurt when you put them on

For comfort and look this is a good length

Now make a lot of teeth and use superglue to glue the teeth to the gum

You’re going to be using a superglue but not any superglue

It needs to have a special active ingredient Cyanoacrylate

It’s perfectly safe when it’s dry

We checked this with the swedish Poison Information Centre

It’s safe to use only if you let it dry properly before you put it in your mouth

If you’re too young you shouldn’t be doing this at all so ask for help

Be very careful with superglue, or you’ll be stuck forever

Just take your time and this will go easy

Let the cyanoacrylate set, then put them in to try them on

Make sure it fits comfortably

Time for the other gum piece

Roll it up like we did with the other one

Press it over the teeth row to cover the edges of the teeth

To really get it in between the teeth we use tweezers

Check to see if it really fits when it’s all there before you glue it

Take it off and glue it in place on the fake gum

Cut off some excess stuff and look at that

Paint the teeth with tooth enamel

Paint these how you want, we want ours a bit rotten

Finish it off with clear nailpolish
