Interacting With Objects Around You

p190 Return to House Rules
 * Issuing new orders to a hireling, beast companion, etc. qualifies as your free ‘interaction’ for your turn.
 * Dropping an item is ‘free’ – it does not count as your interaction for your turn.
 * You can drink a potion as a Bonus Action. Administering a potion to another creature requires your Action.
 * Things like flask of Alchemists Fire or acid are hurled with the Attack action rather than the Use Object action
