Blown Sugar Bubbles

Bring to a boil and add 8 drops tartaric acid. Boil until it reaches 314F. Pour onto a marble slab or a large silpat sheet. When cool enough to handle, pull off balls marble to golf ball size, depending on the size of the bubble you want. Attach to the end of a wooden straw and blow. Twist the bubble and melt the end shut with a spirit burner and cut away with scissors.
