Put a few mL of HCl in a test tube.
Add a small piece of Mg ribbon.
Cover the test tube with another test tube held upside down. This is to collect the hydrogen gas, which is less dense than air.
A flame held near the mouth of the upside-down test tube will make a "squeaky pop" which is the explosion of the hydrogen as it reacts with oxygen in the air.

Depends on how brave you are. You can put a smoldering spinter in the hydrogen gas exhaust line which should flare vigorously once exposed.

Mg + 2HCl = MgCl2 + H2

trap the gas and safely check it for flammibility.

2HCl(aq) + 2Mg(s) = H2(g) + MgCl2(s)
