# What is an Explosive Word™?

This is in the spirit of the What is a Word/Phrase™ series started by JLee with a special brand of Phrase™ and Word™ puzzles.

If a word conforms to a special rule, I call it an Explosive Word™.

Use the following examples below to find the rule.

Hint #1:

Hello -> Hlo, el

• LOL. "Bomb" is not an explosive word. – Marius Sep 26 '16 at 13:34
• Something to do with ASCII code? – Rand al'Thor Sep 26 '16 at 17:05
• @randal'thor Yes – TuxCrafting Sep 26 '16 at 17:08
• im having trouble but perhaps something where the ascii codes count down to 0 or osmething liek that – Avik Mohan Sep 27 '16 at 7:54
• You probably need to provide some hints.. – Sid Oct 13 '16 at 5:50

An Unexplosive Word™ is one where ...

... the sums of the ASCII codes of both the even letters and the odd letters of the word are odd. This also explains Peregrine Rook's finding that the total sum of ASCII codes of such words is always even. For example:

OTHER:     (O:79) + (H:72) + (R:82) = 233;     (T:84) + (E:69) = 153

Because only evenness is important, the sum can be made over the alphabet position (A=1, B=2, etc.) instead.

An Explosive Word™ is a word that isn't Unexplosie™.

As for the name:

I can only assume that it has to do with "exploding" the word into odd and even parts, just like parts are separated in an explosive view.

I really wouldn't have gotten this without the last hint.

• Yep, it's that (filler) – TuxCrafting Oct 13 '16 at 9:15

I haven't checked all of them yet, but could it be that:

ASCII of explosive adds up to an odd number, and ASCII of non-explosive adds to an even number

• well, other than IMPORTANT, but it happens surprisingly often to be just a coincidence... – mr23ceec Sep 27 '16 at 15:01
• Well, other than IMPORTANT, FIRST, LONG, LITTLE, SAME, HAVE and MAKE. Also, why would such a word be called Explosive? – M Oehm Sep 27 '16 at 15:03
• It's just a name, I guess "foobar" was taken that day. ;) – mr23ceec Sep 27 '16 at 15:05
• With this, MAKE and FACT are equal. I think we need a different operation. – Phlarx Sep 27 '16 at 16:16
• (1) $2/3$ ($66.\bar6\%$) of the Explosive Words have an odd total; $100\%$ of the Unexplosive (or Non⋅Explosive) Words have an even total.  This is way too often to be just a coincidence.  (2) Also, FIRST = WORLD.  (3) If you take the character values “modulo” 64 (i.e., you map A → 1, B → 2, etc.), then you get some words of different lengths with the same total; e.g., BE = BAD and GET = HIGH. – Peregrine Rook Sep 27 '16 at 18:43
