Raising the temperature! Pointing 1.2W+ 445nm laser on bulb of spirit thermometer!

Using 445nm diode laser producing no less than 1.2 watts CW. Focused well and waist waved across bulb of standard "spirit" thermometer. Of interest here is the speed the column moves. Yes if the laser is kept still the tube will burst! It's interesting how fast the liquid can move in the column. So fast it actually leaves traces near the top. Typically this is seen with these types of thermometers where they are dropped. (and the shock did not break the tube) The way to "fix" this is to heat it SLOWLY and allow the column to rejoin with the orphaned section. When it cools back down things are normal again. SAFETY NOTICE! Class IV lasers are dangerous! NEVER and I mean NEVER perform any kind of experiment as shown in this video without proper safety precautions. Lasers of this power should NEVER be operated by anyone unfamiliar with class IV laser safety procedure and use of proper personnel protection equipment (PPE) at ALL times. Failure to adhere this warning may result in serious personal injury to yourself or spectators close by.
