Device for blowing bubbles - into desserts( fluffy ) pudding

[melani]

ok, so normally - we just use electric Mixer to make desserts Fluffy - but is there such a Device - specifically for Desserts with a long nozzle or thin hose -to blow those bubbles - in to it - should work on both hot desserts that cool down to cold - or cold desserts -that set to room temperature- I only ever seen this done by Heston Blumenthal - when he made a special dessert using this method ???
