FORMcard is a handy, pocket sized card of strong,meltable bio-plastic that you can use to make, fix and modify the world around you. Just drop it in a cup of hot water and it's ready to use. Because it's card sized, you can keep one in your wallet, toolbox or kitchen drawer so that it's always around when you need to fix something.
This Instructable shows you how to make your own unique ice cubes with FORMcard. It's amazing for mould making and picks up a very high level of detail.
Step 1: Melt the FORMcard
Take a single FORMcard.
Boil a kettle and pour out a cup of hot water. Let it stand for a minute.
Drop the FORMcard in and wait for it to go floppy.
Take it out with a spoon - being careful around the hot water!
Make sure it's okay to handle, it should be warm, but not burning hot. Don't use it if it's too hot!
Step 2: Mould It Onto Something
Squash it on to something.
An orange. A wooden toy. Your nose. A big key maybe?
Remember that it will stick to other plastics if it's really hot. Just check before you squash it into things. Oh - and avoid squashing into fabrics as it can get stuck in the fibres.
Let it go cool on whatever it's moulded around. You can run it under cold water if you're in a rush.
Step 3: Make Your Ice Knuckle!
Fill the mould with water.
Put it in the freezer and wait for it to freeze.
The FORMcard is flexible enough so you can wiggle out the ice easily.
