Here I want to show you how to create a heart out of the plastic film which seals a pack of cigarettes. A nice thing to do if you're hanging around bored in a pub.
Step 1: Pull the plastic off
Pull of the plastic foil about 1,5 cm
Step 2: Turn it 90 Degrees
Turn it around 90 Degrees, so 2 "flaps" are formed
Step 3: Melt and fold them down
Now take a lighter. Melt the edges of the 2 Flaps and fold them down to the middle.
Step 4: Repeat
Repeat the last step 3 times.
Then pull of the plastic completely.
Melt down the pieces of plastic which are standing out of the square. First the two small sides, the the bigger ones.
Step 5: The Square
now you should have a pretty decent square.
Step 6: The notch
Now melt a notch to one of the corners. User a lighter to push it down.
Step 7: The Edges
Now round up the edges. User the bottom of your lighter.
Step 8: Finish
Now your heart is finished and ready to be given to the one you love :-)
Caution: Hot plastic cane hurt you, and gases may be toxic!
