I have been looking for a discussion topic where I could post and get ideas for one-second parties. Is there a topic area for this? Thanks.

I'm not sure what your looking for but I have a few festive 5 second parties
Christmas.....10 finger jingle, jingle, jingle
New years.....10 finger da tah da da...(hold hands like a trumpet)say Happy new year
Halloween.....10 finger boooooo
february......Shoot an arrow and whistle whoo whoo
10 finger ...rasberry with your tounge
I hope some of these help
Ask students to help me invent some too

Those are wonderful, thanks!! I am adding them to my list.

Here are some of the ones I have come up with:

FANFARE!  (trumpets so   so so   so    so    DO!!!)

DRUMROLL!!!! (students do on laps or instr. if they have them.)

REVEILLE! (kids play Reveille on “horns”) If it is a.m., they can end singing "good morning!" where "this morning" is at the end of the tune.

My music colleague, the only teacher I have managed to get to try WBT so far (and she loves it, too), Terri Hoffman, came up with these which I think are so creative!

Give a "seal" of approval to a student/class.   Class claps their arms like a seal(the animal) and makes a seal sound.  (Actually, you clap the backs of your
 hands together keeping your arms straight & downward.)

Give a “round of applause” to a student/class.  Everyone claps, moving their arms in a big circle in front of them.

Oh I have more too.
Disco Applause....Ah Ah Ah Ah, you did a good job, you did a good job! You point diagonally up right and down left like your disco dancing.
Rock and Roll applause.....you air guitar and make a whammy sound like this...bow, bow bow, bow....Hold the imaginary mic to your mouth and scream like a rock star while pointing in the air..."You did a good job"
Train appluase....chugga chugga, chugga chugga, chugga chugga,...pull down the imaginary train whistle and say "good job" like a train whistle

Those are awesome, Barrrm! Thanks for sharing them!
