Quote: "Element 115 has been the subject of many conspiracy theories and works of fiction. I see no reason to believe one particular theory over another (particularly when no evidence is present)."
Completely agree with this.
Quote: "But more importantly, will it blend?"
Let's examine this.
The maximum recorded life of element 115 is ~200ms before it decays into something lower, and the rotary speed of a BlendTec blender is 27'000rpm. This means there will be a blade passing around once every 2.2ms, however there are two Blendtec blender blades, so we can halve that number.
Assuming optimal blending conditions (the blend blade collides with the atom every single time, and the atom exists for 200ms), you will be able to "cut" ununpentium approximately 180 times before it decays.
In conclusion: Yes, it will blend.
