Helium prat

Jag pratar och sjunger "mary had a littla lamb" efter att andas in Helium från en ballong.

Swedish talk -English song with helium. Helum has a much lower density than air, so the sound waves vibrate faster giving a higher frequency.

If you try playing with inhaled Helium, be sure to really concentrate on what you are going to say. The first time your own voice usually feels so strange, you will probably laugh out all the gas after hearing the first syllable. A shame to waste good gas!

Unfortunately the clip doesn't include my normal voice to compare with. You could check some of my other videos.
