Your task is to draft three patent claims to cover your invention. Please make sure to follow the standard format of a claim (X comprising/consisting of Y element(s)).

1. Claim 1 is to be the broadest claim you can draft while maintaining sufficient disclosure to allow a PHOSITA to manufacture the claimed invention. For this question, your claim should be broad enough that at least some variants of the rainbow slinky may be covered.
2. Consider a scenario in which the only prior art is an inflexible, grey coil. Please draft claim 2 in a way that is broad, but likely to be valid under 102 (novelty requirement) and 103 (non-obviousness requirement), as well as under 112 (fully and appropriately described).
3. Claim 3 is a "failsafe" claim: draft a narrow claim you are SURE will be held to be valid under 102, 103, and 112. For this question, it is acceptable to draft a claim such that only the rainbow slinky pictured will be covered.
