it is not dangerous, provided that you do it in a chem lab.
The "glass" is actually quartz, with melting temperature of 1670C. A way too high than you can achieve with silane flame. BTW, the burning silane produces quartz sand which massively deposited on the walls of the glass. So... walls get even thicker! )
If you compare it with this movie "#02 Silanes" (see list related clips on the right) you will easily notice quite different chemical reactiveness.
The magnesium silicide has very low yield of silane, as low as 10-14% of initial silicon content. Contrary, here the yield is up to 99% conversion of silicon part into gaseous silane SiH4.
After reading the notes to this video I was like "OH! Translation put sodim silicide or magnesium silicide, with hydrochloric acid to get silane."

Nearly pure silane is used in glass deposition on silicon wafers.

you guys are little crazy...be careful... it could of melt the glass...

heat sand with maagnesium powder and then put it in a solution of 1 part hydrochloric acid 5 parts water

actually the powder is not magnesium silicide.
