GraviGun

Gravity Gun is a small mod, written by iChun, based off of the Gravity Gun from Half Life 2, that adds a regular Gravity Gun and a Supercharged Gravity Gun. The Gravity Gun allows the player to pick up and place certain blocks/entities. It can also be used to shoot away the object that has been picked up by the player by right clicking. The supercharged variant has a greater range and power.

Recipe
The Gravity Gun is made with one Diamond, one Glowstone, two Iron Ingot, one Obsidian and four Ender Pearls, to craft the Supercharged version, replace the glowstone with a Nether Star, alternatively you can breed bees with the "Lightning Effect", enter a Mystcraft age with the "Charged" symbol, or more simply, activate a Twilight Portal

Trivia

 * Creepers Flung with the supercharged gravity gun will explode upon contact with a solid surface.
 * Picking up a block with the gravity gun and placing it atop a torch will cause it to function similarly to a pickaxe with silk touch.
 * The gun can be exploited to get cheap nether stars by charging it via Twilight Forest portal creation and using an Uncrafting Table to retrieve the star, it costs nine levels to do so.
