Tanglefoot Bag: Throw this round leather bag full of alchemical goo as a grenadelike weapon. When the bag is thrown against a creature (as a ranged touch attack), the bag comes apart and the goo bursts out, entangling the target and then becoming tough and resilient on exposure to air. An entangled creature suffers a -2 penalty to attack rolls and a -4 penalty to effective Dexterity. The entangled character must make a Reflex save (DC 15) or be glued to the floor, unable to move. Even with a successful save, it can only move at half speed.
A character who is glued to the floor can break free with a successful Strength check (DC 27) or by dealing 15 points of damage to the goo with a slashing weapon. A character trying to scrape goo off himself, or another character assisting, does not need to make an attack roll; hitting the goo is automatic, after which the character who hit makes a damage roll to see how much of the goo he happened to scrape off. Once free, a character can move at half speed. A character capable of spellcasting who is bound by the goo must make a Concentration check (DC 15) to cast a spell. The goo becomes brittle and fragile after 10 minutes.
Thunderstone: Throw this stone as a grenadelike weapon. When it strikes a hard surface (or is struck hard), it creates a deafening bang (a sonic attack). Creatures within a 10-foot radius must make Fortitude saves (DC 15) or be deafened. Deaf creatures, in addition to the obvious effects, suffer a -4 penalty on initiative and a 20% chance to miscast and lose any spell with a verbal (V) component that they try to cast.

Or look in the equipment chapter of the PHB - at the end of the chapter, I think.
