One more

Baby F needs to take her vitamins, but she has a problem. There are 4 bottles of vitamins which look the same (her friend E doesn't know any better, and she tore the labels off earlier) but one of them is soy based, and she is allergic to soy! The other three bottles contain different vitamins, and she needs to take 1 of each of them.

There is only one difference between the pills - the right vitamins weigh 1 gram, and the soy based ones weight 1.1 grams. Baby F received a scale for her birthday from her grandfather, the defender of small children and poultry. What a fortuitous gift! The only problem is, the scale is electronic, and the batteries have become worn down from weighing blocks and babydolls. Baby F only has enough battery power to make 1 weighing, so she must use it wisely.

How can she use the scale to accurately determine which pills are safe with only 1 weighing?

Another one - a word one this time

What do the words flour, gone, and thirsty all have in common? (Besides the fact that they all have vowels)

A new one - a bit easier

Here's another numbers one: ;)

If 1=3, and 6=3, and 1-6=11, what do the following equal?
12=?
47+3=?
3-3=?

The next post is not only written backwards, but also reads from bottom to top. Sorry about that.

Alright, here's the answer...

But I'll write it backwards in case someone wants to still work on it.

I'll post a new one later, right now I need to get ready for work.

Another one

I'm feeling generous today.

What do these words have in common: age, blame, curb, dance, evidence, fence, gleam, harm, interest, jam, kiss, latch, motion, nest, order, part, quiz, rest, signal, trust, use, view, win, x-ray, yield, zone?

A new one

Hopefully this one is harder. And hopefully I can get the text to line up.
What row of numbers comes next?

That's a loud CD-ROM drive

Dude, your drive is too loud.

Again, Bob is correct.

Hmm... I'll have to make the next one a little tougher.
