The function like iron grenades in that you can "cast" them while moving, but have a much larger radius, do more damage and stun for 5 seconds instead of 3.
The drawback is that they are considerably more expensive.

How do you make this thing? Where to get the recipe?

Try dropping one of these in the flag room in Warsong Gulch when lots of enemies are there. Truly stupefying results! You can single-handedly grab their flag and run out while they are stunned for FIVE seconds. Remember to wave good bye as you leave...

There's a lot of confusion about this currently. There are basically four types of items that can be made by engineers:

BoE items that can be used by any engineer and traded.
BoP items that can be crafted by a specific specialization, but used by any engineer
Items that require a specific specialization to use.
BoP items that can be crafted by an engineer, but can be used even after engineering is dropped

Gnomish Engineering allows you to craft these items:

Item	Bind on Pickup	Requires Engineering to Use	Requires Gnomish to Use
Gnomish Goggles	Yes	Yes	No
Gnomish Harm Prevention Belt	No	Yes	No
Gnomish Mind Control Cap	No	Yes	No
Gnomish Rocket Boots	No	Yes	No
Ultrasafe Transporter: Gadgetzan	No*	Yes	Yes
World Enlarger	No	Yes	Yes
Gnomish Battle Chicken	Yes	Yes	No
Gnomish Death Ray	Yes	No	No
Gnomish Net-o-Matic Projector	No	Yes	No
Gnomish Shrink Ray	No	Yes	No
Plans: Inlaid Mithril Cylinder	N/A	N/A	N/A
Lil' Smoky	Yes	Yes	No

* This is Bind on Use (not equip).

If your intent is to switch to Goblin after crafting all the goodies (by dropping and re-leveling Engineering), you should probably craft all of these items, but you must craft Gnomish Goggles, Gnomish Battle Chicken, Gnomish Death Ray, and Lil' Smoky (these are Bind on Pickup) or you will lose access to these items permanently (unless you drop and re-level Gnomish Engineering again.)

Ultrasafe Transporter: Gadgetzan and World Enlarger cannot be used by a non-gnomish engineer, so you can skip crafting these if you're planning on switching.

NOTE: Gnomish Death Ray doesn't require Engineering to use, so technically, you could level Engineering to craft this item, and drop it and still be able to use it.

Goblin Engineering allows you to craft these items:

Item	Bind on Pickup	Requires Engineering to Use	Requires Goblin to Use
Goblin Rocket Boots	No	No	No
Recipe: Goblin Rocket Fuel	No	N/A	N/A
Goblin Mortar	No	Yes	No
Goblin Mining Helmet	Yes	Yes	No
Goblin Construction Helmet	No	Yes	No
The Big One	No	Yes	No
Goblin Bomb Dispenser	Yes	Yes	No
Goblin Rocket Helmet	No	Yes	No
Goblin Sapper Charge	No	Yes	No
Goblin Dragon Gun	Yes	No	No
Goblin Mortar	No	Yes	No
Pet Bombling	Yes	No	No
Dimensional Ripper - Everlook	No*	Yes	Yes

* This is Bind on Use (not equip).

If your intent is to switch to Gnomish after crafting all the goodies (by dropping and re-leveling Engineering), you should probably craft all of these items, but you must craft Goblin Mining Helmet, Goblin Bomb Dispenser, Goblin Dragon Gun, and Pet Bombling (these are Bind on Pickup) or you will lose access to these items permanently (unless you drop and re-level Goblin Engineering again.)

NOTE: I recommend you go Gnomish first because most items crafted by Goblin are consumable, whereas Gnomish is toys and trinkets that can be used after you switch. If you do Goblin first, you'll not be able to craft some of the most powerful explosives in the game for yourself and need to buy them regularly if you want to use them.

Dimensional Ripper - Everlook cannot be used by a non-goblin engineer, so you can skip crafting these if you're planning on switching.

NOTE: Goblin Dragon Gun doesn't require Engineering to use, so technically, you could level Engineering to craft this item, and drop it and still be able to use it.

Some of the info here is wrong Solid Dynamite makes 2 bombs for 1 Solid Blasting Powder and 1 Silk Cloth so its 1/2 the materials implies if you're looking at the break down.

Total mat requirements are :
4 Mithril Bar
8 Solid Stone
3 Silk Cloth
1 Mageweave Cloth
1 Firebloom
1 Volatile Rum
1 Leaded Vial
And an alchemist who can make Goblin Rocket Fuel
