Largest Product

Using all the digits from 1 to 7, what two numbers have the largest product? For example, 1234 x 567 = 699678 but you can do much better than that.

742 x 6531 = 4,846,002.

A similar problem can be found in L.A. Graham’s Ingenious Mathematical Problems and Methods with a range of 1 to 9, but the principle remains the same – the numbers with the smallest difference produce the largest product. You start out with the highest two digits, 7 and 6, then attach 5 and 4, putting the smaller of the two digits with the larger number, giving you 74 and 65. The next two highest digits are 3 and 2, giving you 742 and 653. Finally, you add the 1 to the lower number. Page 80 has the details of that solution.

Stars Awash in a Sheen of Light

Stars awash in a sheen of light
It calls out loud in vile delight.
Listeners endure in fright.
Vicious brute that reigns at night,
Evil whelped of heinous bite,
Renewed by wax, it regains might.
A leading way to slay the beast,
Get the hidden weapon thus released.

What is this describing?
Hint: The first letter of each line has a clue

A werewolf (vulnerable to silver bullets).

What Looks Like Food

What looks like food, tastes like food, smells like food, sounds like food when you cook it, is grown in dirt like food, fills up your stomach like food, but is not food?

A poisonous mushroom. Since some types of mushrooms are edible, it can be very hard to distinguish between a safe mushroom and one that will kill you. Food is defined as a substance consumed to provide nutrition, therefore a poisonous mushroom that kills you doesn’t qualify as food, even though it shares all of the traits of a regular mushroom.

Other valid answers include anything that’s edible, resembles food, but is poisonous.
